diketahui fungsi f(x)=x+2 dan fungsi g(x) =x2-3x +4 fungsi komposisi (gof)(x)=

langsung aja y

(gof)(x) = g{f(x)}

= f(x)² - 3f(x) + 4
= (x+2)² - 3(x+2) + 4
= x² + 4x + 4 - 3x - 6 + 4
= x² + x + 2

semoga berguna +_+

Bab Fungsi
Matematika SMA Kelas X


f(x) = x + 2
g(x) = x^2 - 3x + 4


(gof)(x)
= g(f(x))
= g(x+2)
= (x+2)^2 - 3(x+2) + 4
= x^2 + 4x + 4 - 3x - 6 + 4
= x^2 + x + 2

Semoga membantu;)
