3. Diketahui f(x) = 2x – 1 dan g(x) = x+7/3x-2, X 2260 2/3, Tentukan:, a. (g o f) (x), b. (gof)-\xb9 (x)

Jawaban:

Penjelasan dengan langkah-langkah:

f(x) = 2x – 1

g(x) = (x + 7)/(3x – 2)

Nilai (g o f)(x) :

= g(f(x))

= g(2x – 1)

= (2x – 1 + 7) / 3(2x – 1) – 2

= (2x – 6)/(6x – 3 – 2)

= (2x – 6)/(6x – 5)
