X = -4 As g(x) is replaced by g(-4) plug in -4 for x inside the equation. g(-4) = (-4) - 1g(-4) = -5 Plug in -4 for x in f(x)f(-4) = 4(-4) - 4f(-4) = -16 - 4f(-4) = -20 Now solve for f(x) over g(x) remember, f(x) = -20, and g(x) = -5 -20/-5 = 4 4 should be your answer hope this helpsClick to let others know, how helpful is it
