1. The problem statement, all variables and given/known data F(x)=√x G(x)= 2/(x-4) Find g(f(x)) and its domain 2. Relevant equations 3. The attempt at a solution I am having trouble finding the domain for this composition. I know that g(f(x))= 2/(√x)-4 I believe that for the domain you combine the domain of the input (f(x)) and the output (g(f(x)). This would then be x > 0 (for f(x)) and x≠16 in g(f(x)). The answer key that I have says that the answer is x>0, x≠4 Where am I going wrong? Why does it disregard 16? Thanks!
