Exponential functions are mathematical functions that involve a variable as an exponent, such as 2^x or 3^x. These types of functions can be found in many real-life situations and can help to model and predict certain phenomena. Here are a few examples of exponential functions in the real world:

1. Population growth: The population of a species or group of organisms can often be modeled using an exponential function. For example, if a population has a constant growth rate, its size will increase at an exponential rate. This means that each successive generation will be larger than the last, leading to exponential population growth.

2. Compound interest: When money is invested at a fixed interest rate, the amount of money earned can be modeled using an exponential function. For example, if someone invests \$100 at a 5% annual interest rate, they will earn \$5 in the first year. However, if the money is left to compound, meaning that the interest is reinvested and added to the principal, the amount of money earned will increase exponentially.

3. Exponential decay: Exponential functions can also be used to model situations where a quantity decreases at a constant rate. For example, the radioactivity of a substance may decrease over time in an exponential fashion. This type of exponential decay can also be seen in the decay of isotopes, such as carbon-14, which is used in radiocarbon dating.

4. Computer processing power: The processing power of computers has increased exponentially over the years, following what is known as Moore's Law. This law, named after Intel co-founder Gordon Moore, states that the number of transistors on a computer chip will double approximately every two years, leading to an exponential increase in processing power.

In conclusion, exponential functions can be found in many real-life situations, including population growth, compound interest, exponential decay, and computer processing power. These functions can help to model and predict certain phenomena and can have significant impacts on various aspects of our lives.

## Applications of Exponential Functions

Exponents are used in Computer Game Physics, pH and Richter Measuring Scales, Science, Engineering, Economics, Accounting, Finance, and many other disciplines. In economics exponential functions are important when looking at growth or decay. Microbes grow at a fast rate when they are provided with unlimited resources and a suitable environment. Students typically explore the mathematics of reflection during a lesson on graphing in the coordinate plane, within the wider context of geometry. These functions are used in many real-life situations.

To form an exponential function, we make the independent variable the exponent. They are generally grown for decorative purposes. What careers use exponential functions? We have to find the constant Î»with the given information. Exponential Growth situations when graphed look like the diagram below. Arrange for a good supply of food and water. The amount of NEW cells depends on how many cells there are at any moment. Have you noticed green coloured mold on your bread spoiling your breakfast in a few hours? This means that the population will reach 450,000 around 2041.

Bacteria reproduce with the help of a process called binary fission in which the parent cell gets divided into two daughter cells. In the latter case, I think it's used for theoretical simulations of mind-bending complexity, such as how a machine might rattle itself to bits. What are Exponential Functions? One cancer cell can make another, and that pair can now make another pair, and quartet can make another quartet. What are 4 applications that can use logarithm functions? Which is an example of reflection? Millions of people have already died of cancer, and many more are suffering from it, and the worst note is that cancer cells divide exponentially, if not treated. Exponential decay Similar to how it is possible for one variable to grow exponentially as a function of another, it is also possible for the variable to decrease exponentially. Hence, it clearly follows exponential growth. Almost everyone has come across the green discolouration which ruins the food and spreads quite fast.

Just as with other parent functions, we can apply the four types of transformationsâshifts, reflections, stretches, and compressionsâto the parent function. However, the rate at which food items gets spoiled can be reduced by processes such as salting and smoking. To reflect about the y-axis, multiply every x by -1 to get -x. For instance, during the influenza pandemic of 1918, the rate of patients suffering from flu increased and, therefore, it was considered an exponential growth of the disease. Fire spreads at a rapid rate because there exists an exponential relationship between the fire and the combustible objects. The circulation of data on the internet is typically exponential in nature as the data gets passed on from one person to the other, the recipients of the content further pass on the information to multiple users, and the process goes on and on. .

Plotting these points and graphing the curve, we have the following: This is an example of using exponential functions to model population growth. Patient Count during a Pandemic A pandemic is an epidemic that gets spread to more than one continent and affects people on a global scale. They comprise a business model that involves recruiting members that are paid on the basis of the number of members they further enrol. Spread of Virus The spread of a virus generally follows exponential growth. Rice on the Chess Board Rice on the chessboard is an ancient story that involves the concept of exponential growth. Graph exponential functions using transformations. What happens in a function when it is reflected? For instance, when the nucleus of a uranium atom gets bombarded by neutrons externally, each nucleus gets broken into two congruent parts.

How much money will there be in the savings account after 10 years? Compound interest Compound interest is an application of exponential functions that is commonly found in our day-to-day life. Suppose you are studying the effects of an antibiotic on a certain bacteria. That depends whether we're talking about a general definition of an exponential function or a technical definition using an exponent of Euler's constant. Due to their exponential growth, they often end up clogging the rivers and blocking sunlight and oxygen to the organisms in the water. The most important applications are related to population growth, exponential decline, and compound interest. The actual energy from each quake is a power of 10, but on the scale we simply take the index value of 1, 2, 3, 4, etc rather than the full exponent quantity.

Example 1: Time Between Geyser Eruptions The number of minutes between eruptions for a certain geyser can be modeled by the exponential distribution. Similarly, economic growth is yet another example of exponential growth in real life. This rate at which the population is decreasing remains constant, but as the population continues to decrease, the overall decline becomes less and less steep.
