Halo kakak-kakak, boleh minta pertolongannya 😭🙏

f(x) = 3x - 9 g(x) = (1/3)x h(x) = 9x a. (f o g)x = 3((1/3)x) - 9 = (3x/3) - 9 (g o f)x = (1/3).(3x - 9) = (3x/3) - (9/3) = x - 3 (g o h) = (1/3).(9x) = 9x/3 = 3x (h o f) = 9.(3x - 9) = 27x - 81 b. (f o g)(3) = (3.3/3) - 9 = (9/3) - 9 = 3 - 9 = -6 c. (g o h)(3) = 3.3 = 9 d. (g o f)(3) = 3 - 3 = 0 e. (h o f)(3) = 27.3 -81 = 81 - 81 = 0
