F(×)=×^+5×-3 G(×)=×-3 Cari A.fog (3) B.gof(-1) Tolong jawab dengn lengkap dan cepat ya

Materi : Fungsi Komposisi



f(x) = x² + 5x - 3
f(0) = 0² + 5(0) - 3
      = -3
f(-1) = (-1)² + 5(-1) - 3
       = 1 - 5 - 3
       = -7

g(x) = x - 3
g(3) = 3 - 3 = 0
g(-7) = -7 - 3 = -10

fog(3)
= f(g(3))
= f(0)
= -3

gof(-1)
= g(f(-1))
= g(-7)
= -10

a. fog(3)
= f(g(3))
= f(0)
= -3

b. gof(-1)
= g(f(-1))
= g(-7)
= -10

semoga membantu
