Expert Answer

Step 1

To describe the exponential function, law of exponents, describe the difference between exponential function and simple power function, define the real-world phenomena.

Step 2

Explanation:

 

Exponential function:

An exponential function is a mathematical function of the following form.

 F(x) =a x, where x is a variable, and a is the constant called the base of the function.

The most commonly used base is the transcendental number (e) which is equal to approximately 2.71828.

Thus, the exponential function become f(x) = ex
