Question

Consider the exponential function f(x) =1/5(15x). What is the value of the growth factor of the function?

A. 1/5

B. 1/3

C. 5

D. 15

Answer 1

The answer is 100% D - 15

Answer 2

we know that

An exponential function is a function where the input, x, appears in the exponent.

the equation of an exponential function usually looks like:

`y=ab^(x)`

where

a is a number called the initial value

b is a number called the growth factor

In this problem

we have

`f(x) =(1)/(5)(15^(x))`

where

`(1)/(5)` -------> is the initial value

`15` ------> is the growth factor

therefore

the answer is the option

`D. 15`
