Diketahui f(x) = x2 - 5x 1 dan g(x) = x 2. komposisi fungsi (fog)(x) =

[tex](f○g)(x) = [/tex]

[tex]f(g(x)) = [/tex]

[tex]f(x+2)=[/tex]

[tex] {(x+2)}^{2} - 5(x + 2) + 1 = [/tex]

[tex] (x+2) (x+2) - 5(x + 2) + 1 = [/tex]

[tex] x(x+2)+2(x+2) - 5(x+2) + 1 = [/tex]

[tex] {x}^{2}+2x+2(x+2)-5(x+2)+1=[/tex]

[tex] {x}^{2}+2x+2x+4-5(x+2)+1=[/tex]

[tex] {x}^{2}+4x+4-5(x+2)+1=[/tex]

[tex] {x}^{2}+4x+4-5x+10+1=[/tex]

[tex] {x}^{2}+4x-5-5x=[/tex]

[tex] {x}^{2}+x-5[/tex]

Jadi, fungsi komposisi (f○g)(x)=x5.
