diketahui f(x)=-2x+3 dan g(x)=x²-4x+5.komposisi fungsi gof(x)=.....

[tex]gof(x) = g(f(x)) \\ g(x) = {x}^{2} - 4x + 5 \\ g(f(x)) = {(f(x))}^{2} - 4(f(x)) + 5 \\ g(f(x)) = {( - 2x + 3)}^{2} - 4( - 2x + 3) + 5 \\ g(f(x)) = {4x}^{2} + 9 + 8x - 12 + 5 \\ g(f(x)) = {4x}^{2} + 8x + 2 \\ g(f(x)) = {2x}^{2} + 4x + 1[/tex]
