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

[tex](gof)(x) = g(2 - x)[/tex]

[tex](gof)(x) = {(2 - x)}^{2} + 5 \: (2 - x)[/tex]

[tex](gof)(x) = ({x}^{2} - 4x + 4) + (10 - 5x)[/tex]

[tex](gof)(x) = {x}^{2} - 4x + 4 + 10 - 5x[/tex]

[tex](gof)(x) = {x}^{2} - 4x - 5x + 4 + 10[/tex]

[tex](gof)(x) = {x}^{2} - 9x + 14[/tex]
