If f(x) = root_(2-x) and g(x) = root_x, find fog and fof

Question

Suresh Chand · Accepted Answer

Solution: Let (f(x) = sqrt{2-x}) and (g(x) = sqrt{x}) Then fog(x) = f(g(x)) = (f(sqrt{x})) = (sqrt{2-sqrt{x}}) and fof(x) = f(f(x)) = (f(sqrt{2-x})) = (sqrt{2-sqrt{2-x}})

If f(x) = \(\sqrt{2-x}\) and g(x) = \(\sqrt{x}\), Find fog and fof
