How are the functions f (x) = 16 Superscript x and g (x) = 16 Superscript one-half x related?

The output values of g(x) are one-half the output values of f(x) for the same value of x.
The output values of g(x) are one-quarter the output values of f(x) for the same value of x.
The output values of g(x) are the square root of the output values of f(x) for the same value of x.
The output values of g(x) are the square of the output values of f(x) for the same value of x.
