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 :

Exponential growth function is defined as

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

Now we compare all the given functions,

1)

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

2)

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

3)

It is a linear function.

4)

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

Therefore, Option 2 is correct.
