find the range of the function.
g(x) = 5 + (square root of) (4  x)
please show all steps.

The range of a (real) function is limited by the quantity inside the squareroot radical, namely 4x≥0
Since the rest of the function is a polynomial, the above is the only limitation on the range.
Range of g(x) : (∞ 4]
