Answer:

D. All positive real numbers

Step-by-step explanation:

The range of a function f(x) are all the possibles values that f(x) can take. So in  the function of the question it doesn't matter what value takes x, f(x) is always going to be a positive number. For example:

f(0)=4^{0}=1

f(-1)=4^{-1}=1/4

f(2)=4^{2}=16

Then, the range of f(x) is all positive real numbers.
