Answer:

Option C.

Explanation:

The general form of exponential growth function is


f(x)=ab^x

where, a is initial values and b is growth factor, b>1.

The given function are


f(x)=4(0.07)^x


f(x)=2(0.44)^x


f(x)=(1)/(2)(6)^x


f(x)=7((1)/(2))^x

In functions 1,2, and 4 the values of b are 0.07, 0.44 and 1/2 respectively. The values of b are less than 1. It means they represent exponential decay.

In function 3, the values of b is 6, which is greater than 1. It means it represent exponential growth.

Therefore, the correct option is C.
