If f (x) = x+4/x, g (x) = x-2, and h (x) = 4x1, what is (fhg) (x)

Given h (x) = sqrt (4x + 1), determine two functions f (x) and g (x) which, when composed, generate h (x). Since the square root is "on" (or "around") the " 4x + 1 ", then the 4x + 1 is put inside the square root. I need to take x, do " 4x + 1 " to it, and then take the square root of the result: g (x) = 4x + 1, f (x) = sqrt (x), and h (x) = (f o g) (x).
