<u>Answer:</u>

The correct answer option is B. f ( x ) = 0 . 2 5 ( 5 . 2 5 ) ^ x.

<u>Step-by-step explanation:</u>

If the numbers are positive along with the base of the exponent which must be greater than 1, then it an exponential growth function.

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

Here the numbers are positive but the base of the exponent is 0.25 which is less than 1 so it is not an exponential growth function.

2. f ( x ) = 0 . 2 5 ( 5 . 2 5 ) ^ x:

Positive numbers with base of the exponent greater than 1, therefore it is an exponential growth function.

Answer: Second Option

f(x)=0.25(5.25)^x

Step-by-step explanation:

The exponential growth functions have the following form:

f(x) = a(b)^x

Where a is the main coefficient, b is the base and x is the exponent.

For this type of functions the base b must always be greater than 1. Otherwise it would be an exponential decay function

Among the options given, the only function whose base is greater than 1 is the second option:

f(x)=0.25(5.25)^x
