See below.

Explanation:

The minimum value (16x4) is 0 for real numbers.

Since x4 is always positive maximum value of radicand is 16

If including both positive and negative outputs the range is:

[4,4]

For positive output [0,4]
For negative output [4,0]

Theoretically 'f(x)=16x4 is only a function for either positive or negative outputs, not for both.i.e:

f(x)=±16x4 is not a function.
