Mohon dijawab ya!
1. Diketahui fungsi f(x) = x² dan g(x) = 3x-4
Tentukan:
a. (fog) (x)
b. (gof) (x)
c. (fog) (1)
d. (gof) (-1)

Answer 1

A. (fog) (x) =f (g (x))
= (3x-4)^2
=9x2-24x+16
B. (gof) (x) = g (f (x))
=3 (x^2)-4
=3x^2-4
C. (fog) (1) =9 (1) ^2-24 (1) +16
=9-24+16
=1
D. (gof) (x) =3 (-1)-4
=-3-4
=-7
