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 would have to be 15.

Answer 2

Option: d is the correct answer.

d. 15

Explanation:

We are given a exponential function as:

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

We know that in general a exponential function is represented by:

`f(x)=ab^x`

where a is the initial amount and b represents a growth factor if it is strictly greater than 1 and a decay factor if 0<b<1

Hence, the value of the growth factor of the function is:

d. 15
