Diketahui fungsi f(x) = 4x +2 , g(x)= 2x+8 , dan h(x) = x²- 5x tentukan

A. f(x) = 4x + 2
f(5) = 4 x 5 + 2 = 22

b. g(x) = 2x + 8
g(6) = 2 x 6 + 8 = 20

c. h(x) = x kuadrat – 5x
h(4) = 4 kuadrat – 5 x 4 = -4

d. (gof)(x) = 8x + 12
(gof)(2) = 8 x 2 + 12 = 28

e. (fog)(x) = 8x + 34
(fog)(1) = 8 x 1 + 34 = 42

f. (hof)(x) = 8x kuadrat – 4x – 6
(hof)(2) = 8 x 2 kuadrat – 4 x 2 – 6
= 8 x 4 – 8 – 6 = 18

cara d – f terlampir yaa

semoga membantu
