If: f (x) = 3(x+1)^2 (the last 2 means square) h(x) = 2/3 Ö(1-x) +3 (the square root is of 1-x only NOT 3) I need to figure out the signs. what is (h o f)(x)?? Thank you very much .

Thank you very much . Are these the equations you meant to type? If so, plug f(x) in for x in the g(x) equation like so:

Thank you very much . That means replace the x in h by the term of f: Try to simplify the last term - but it isn't necessary according to the wording of your question.
Sorry about the wording.... I need to simplify it too....
