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).
