Jika F(X)=2x+1 dan g(X)=4-½x maka (God)(X)=
![]()
Jawab:
(g o f)(x) = [tex]\frac{9}{2} -x[/tex]
Penjelasan dengan langkah-langkah:
f(x) = 2x + 1
g(x) = [tex]4-\frac{1}{2}x[/tex]
(g o f)(x) = g(f(x))
= g(2x + 1)
= [tex]4-\frac{1}{2} (2x-1)[/tex]
= [tex]4-x+\frac{1}{2}[/tex]
= [tex]\frac{9}{2} -x[/tex]
