Question 948363: Let f(x) = √(x-4) - 1 and g(x) = (x+1)^2+2x. Find (gºf)(x) and simplify your answer. Final answer should not have any parentheses.
Is my answer correct?
(√(x-4) -1+1)^2 +2(√(x+4) - 1)
= x-4+2√(x-4) + 2
= x+2√(x-4) - 2

You can put this solution on YOUR website! You are using the definition well, g(f(x)), using f and the input for g. You made a sign mistake in your work, so go back and fix that and then do the steps better.
