Which is an exponential growth function? f(x) = 6(0.25)x f(x) = 0.25(5.25)x f(x) = –4.25x f(x) = (–1.25)x

Option 2      

Step-by-step explanation:

To find : Which is an exponential growth function?

Solution :

The exponential function general form is

When b>1 then the function is exponentially grow.

When b<1 then the function is exponentially decay.

1)

On comparing with general form, a=6 and b=0.25<1.

Function is not exponential growth function.

2)

On comparing with general form, a=0.25 and b=5.25>1.

Function is an exponential growth function.

3)

On comparing with general form, a=1 and b=-4.25<1.

Function is not exponential growth function.

4)

On comparing with general form, a=1 and b=-1.25<1.

Function is not exponential growth function.

Therefore, option 2 is correct.
