PLEASE HELP!
The function f ( x ) = 2 ⋅ 4 ^x can be used to represent an exponential growth curve. What is the multiplicative rate of change of the function?

Group of answer choices

2

4

8

32

The multiplicative rate of change is 4

Step-by-step explanation:

The multiplicative rate of change is the common ratio of the exponential growth curve.

The given exponential growth curve is

This function tells us that, when x=0, f(0)=2.

The subsequent terms can be obtained by multiplying by 4 repeatedly.

Therefore the multiplicative rate of change is 4.

The correct answer is option 2

good luck!
