If:
x = - 7
We know that:
[tex]f(x) = x^2 + 6[/tex] → [tex]f(-7) = (-7)^2 + 6 = 49 + 6 = 55[/tex]
[tex]g(x) = \frac{x+8}{x} [/tex]
Soon:
[tex](gof)(f(-7)) = \frac{x+8}{x}[/tex]
[tex](gof)(55) = \frac{55+8}{55}[/tex]
[tex]\boxed{\boxed{(gof)(55) = \frac{63}{55}}}\end{array}}\qquad\quad\checkmark[/tex]
