I'm assuming that the max point of f(x) = (2,4) f(x) = 4 - |2x| g(x) = 4 - x f(g(x)) = 4 - |2(4-x)| = 4 - |8 - 2x| g(f(x)) = 4 - 4 + |2x| = |2x| f(f(x)) = 4 - |2 (4 - |2x|)| = 4 - |8 - |4x|| g(g(x) = 4 - (4 - x) = x Just plug in the values for the ans: f(g(x)) = 4 - |8 - 2x| g(f(x)) = |2x| f(f(x)) = 4 - |8 - |4x|| g(g(x) = x
