pliss di jwb ya diketahui f(×)=×^2 +3×- 1,g(×)=2× +5, dan h(×)= 1-×. Rumus komposisi fungsi ( g o f o h)(×)=...

pertama-tama cari foh(x) = (1 - x)^2 + 3(1 - x) - 1 = x^2 - 5x + 3

kemudian gofoh(x) = 2(x^2 - 5x + 3) + 5 = 2x^2 - 10x + 11

Kelas 10 Matematika
Bab Fungsi Komposisi

(gofoh) (x) = (gof) (1 - x)
(gofoh) (x) = g ((1 - x)² + 3 (1 - x) - 1)
(gofoh) (x) = g (1 - 2x + x² + 3 - 3x - 1)
(gofoh) (x) = g(x² - 5x + 3)
(gofoh) (x) = 2 (x² - 5x + 3) + 5
(gofoh) (x) = 2x² - 10x + 6 + 5
(gofoh) (x) = 2x² - 10x + 11
