Question

jika f(x)= 3x-2/x-4 dan g(x)=2x+1, rumus (gof) (x) adalah

Answer 1

Penjelasan dengan langkah-langkah:

f(x) = (3x - 2)/(x - 4)

g(x) = (2x + 1)

(gof)(x) = g(f(x))

(gof)(x) = 2[(3x - 2)/(x - 4)] + 1

(gof)(x) = [(6x - 4)/(x - 4)] + [(x - 4)/(x - 4)

(gof)(x) = [(6x - 4) + (x - 4)] / (x - 4)

(gof)(x) = (7x - 8)/(x - 4)
