Check out these kinds of exponential functions in this tutorial!If something decreases in value at a constant rate, you may have exponential decay on your hands.
Again, exponential functions are very useful in life, especially in the worlds of business and science.
If you’ve ever earned interest in the bank (or even if you haven’t), you’ve probably heard of “compounding”, “appreciation”, or “depreciation”; these have to do with exponential functions.
These types of equations are used in everyday life in the fields of Banking, Science, and Engineering, and Geology, as well as more fields.
We learned about the properties of exponents here in the Exponents and Radicals in Algebra Section, and did some solving with exponents here.
Just remember when exponential functions are involved, functions are increasing or decreasing very quickly (multiplied by a fixed number).
That’s why it’s really good to start saving your money early in life and let it grow with time.
Examples, videos, worksheets, and activities to help Pre Calculus students learn how to apply exponential functions.
Compound Interest (Finite Number of Calculations) One real world application of exponential equations is in compound interest.
Also note that Factoring with Exponents and Solving Exponential Equations after Factoring can be found in the Advanced Factoring section here.
And when we study Geometric Sequences, we’ll see that they are a discrete form of an exponential function.
