diketahui f(x) = x-3 , (g o f) (x) = (x+3)² . ditanya g (-4) = Tolong ya kak bntuannya , trimah kasih

Langsung aja y

(gof)(x) = g{f(x)}
(x+3)² = g(x-3)

x - 3 = -4
x = -4 + 3
x = -1

g(-4) = (-1 + 3)²
g(-4) = (2)²
g(-4) = 4

semoga berguna +_+

Pembahasan :
Gof(x) = (x + 3)²
G(f(x)) = (x + 3)²
G(x - 3) = (x + 3)²

Misal x - 3 = a
x = a + 3

G(a) = (a + 6)²
G(-4) = (-4 + 6)²
G(-4) = 2²
G(-4) = 4
