tolong kk baik cantik manissa mwheheheh ​

Answer 1

(fogoh)(x) = 6x - 5

Penjelasan dengan langkah-langkah :

Diketahui

• f(x) = 2x + 3
• g(x) = x - 2
• h(x) = 3x - 2

Ditanya

• (fogoh)(x) …?

Jawaban

(fogoh)(x) = f(g(h(x)))

(fogoh)(x) = f(g(3x - 2))

(fogoh)(x) = f((3x - 2) - 2)

(fogoh)(x) = 2((3x - 2) - 2) + 3

(fogoh)(x) = 2((3x - 2 - 2) + 3

(fogoh)(x) = 2(3x - 4) + 3

(fogoh)(x) = 6x - 8 + 3

(fogoh)(x) = 6x - 5

Answer 2

Diketahui

• f(x) = 2x + 3
• g(x) = x - 2
• h(x) = 3x - 2

Ditanya

• fogoh(x)

Penyelesaian

Cari fog(x)

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

fog(x) = 2x - 4 + 3

fog(x) = 2x - 1

Selanjutnya, cari fogoh(x)

fogoh(x) = 2(3x - 2) - 1

fogoh(x) = 6x - 4 - 1

fogoh(x) = 6x - 5
