g(x) = 2x+p
(fog)(x) = (gof)(x)
p?
mohon dijawab menggunakan cara ya kak terimakasih banyak
F(x) = 3x-4
Jawaban:
p = – 2
Penjelasan dengan langkah-langkah:
f(x) = 3x – 4
g(x) = 2x + p
(fog)(x) = 3(2x +p) – 4
= 6x + 3p – 4
(gof)(x) = 2(3x – 4) + p
= 6x – 8 + p
maka :
(fog)(x) = (gof)(x)
6x + 3p – 4 = 6x – 8 + p
6x + 3p – 4 – 6x + 8 – p = 0
2p + 4 = 0
2p = – 4
p = – 2
