. let f(x) = Vx-4 , g(x) = (x+1)^2, find (f o g)(x) and (f o g)(2)

also

let f(x) = 2x-4, g(x) = x^2+1 find (gof) I got 2x^2 - 15 and was incorrect

Hi;

. let f(x) = Vx-4 , g(x) = (x+1)^2, find (f o g)(x) and (f o g)(2)

I am assuming

let f(x) = 2x-4, g(x) = x^2+1 find (gof) I got 2x^2 - 15 and was incorrect
