Answer 1

Verified answer

Jawab: nomor 1 & 2

Penjelasan dengan langkah-langkah:

1) F(x) = 2x + 5

G(x) = 3x - 4

(fog)(x) = 2(3x-4) + 5

6x - 8 + 5

6x + 3

•(gof)(x) = 3(2x+5) - 4

6x + 15 - 4

6x + 11

2) f(x) = 5 - 2x

g(x) = 2x - 4

•(fog)(x) = 5 - 2(2x-4)

5 - 4x + 8

-4x + 13

•(gof)(x) = 2(5-2x) - 4

10 - 4x - 4

-4x + 6
