Nevermind, sqrt(x + 2) is the right answer. I finally found it!
Find g for f(g(x)) = 5 + x when f(x) = x^2 + 3
Does anyone know how to find g?
I tried the following:
sqrt(x) results in x + 3 which is wrong...
sqrt(x) + 2 results in x + 4sqrt(x) + 7 which is wrong...
etc...
Nothing seems to work.... How do I do this? Please help!
