diketahui fungsi f(x)=x²-4 dan g(x)=x+3,tentukan(fog)(-2)=

tolong dong ka​

⟩ Komposisi Fungsi

» Diketahui

  • f(x) = x² - 4
  • g(x) = x + 3

» Ditanya

  • (fog)(-2)

» Penyelesaian

(fog)(-2) = f(g(-2))

(fog)(-2) = (g(-2))² - 4

(fog)(-2) = ((-2) + 3)² - 4

(fog)(-2) = (1)² - 4

(fog)(-2) = 1 - 4

(fog)(-2) = -3
