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\

Answer:

Option 2 -
f(x)=0.25(5.25)^x

Explanation:

To find : Which is an exponential growth function?

Solution :

Exponential growth function is defined as
y=ab^x

Where b=1+r is the growth rate function or b>1.

Now we compare all the given functions,

1)
f(x)=6(0.25)^x

Here, b<1 so it a exponential decay function.

2)
f(x)=0.25(5.25)^x

Here, b>1 so it a exponential growth function.

3)
f(x)=-4.25x

It is a linear function.

4)
f(x)=(-1.25)^x

Here, b<1 so it a exponential decay function.

Therefore, Option 2 is correct.
