## What are examples of exponential functions in real life?

Exponential functions are often used to represent real-world applications, such as bacterial growth/decay, population growth/decline, and compound interest. Suppose you are studying the effects of an antibiotic on a certain bacteria.

What is an example of an exponential equation?

In other words, when an exponential equation has the same base on each side, the exponents must be equal. For example, consider the equation 34x−7=32×3 3 4 x − 7 = 3 2 x 3 . To solve for x, we use the division property of exponents to rewrite the right side so that both sides have the common base 3.

### What is a real life example of exponential growth or decay?

So, the process of cooling of a kettle after the heat is off is a good example of an exponential decay. This example prompts to a conclusion that every process with a speed of change proportional to its value exhibits the exponential dependency. Another typical example is a population grows.

What would be an example of exponential growth?

Some examples of exponential growth are population growth and financial growth. The information found, can help predict what a population for a city or colony would be in the future or what the value of your house is in ten years.

#### What is a real life example of a linear function?

Linear modeling can include population change, telephone call charges, the cost of renting a bike, weight management, or fundraising. A linear model includes the rate of change (m) and the initial amount, the y-intercept b .

What are the two methods for solving exponential equations?

How to Solve Exponential Equations

• Equating Two Exponents with the Same Base.
• Equating an Exponent and a Whole Number.
• Using Logs for Terms without the Same Base.

## What makes an exponential equation?

Exponential equations are equations in which variables occur as exponents. For example, exponential equations are in the form ax=by . To solve exponential equations with same base, use the property of equality of exponential functions . If b is a positive number other than 1 , then bx=by if and only if x=y .

What are some examples of exponential growth?

### What decays exponentially in real life?

Radioactive Decay Radioactive decay of the isotopes of radioactive elements is a prominent example of exponential decay in real life.
