diketahui f(x) = 2x-1 dan g(x) = 3x+4 jika h(x) = (f x g) (x) rumus fungsi h (x-1)

Kelas 10 Matematika
Bab Fungsi Komposisi

h(x) = (f . g) (x)
h(x) = (2x - 1) . (3x + 4)

h(x - 1)
= (2(x - 1) - 1) . (3(x - 1) + 4)
= (2x - 2 - 1) . (3x - 3 + 4)
= (2x - 3) (3x + 1)
= 6x² + 2x - 9x - 3
= 6x² - 7x - 3
