Answer:
63/55
Step-by-step explanation:
Assuming [tex]f(x) = x^2+6[/tex] and [tex]g(x) = x + {8}{x}[/tex]. Find ( g o f)( -7) by substituting f into g. Then -7 into the new expression.
( g o f)( -7) =
[tex]\frac{(x^2+6) +8}{x^2+6} \\\\ \frac{((-7)^2+6) + 8}{(-7)^2+6} \\\\ \frac{49+6+8}{49+6}\\\\ \frac{55 + 8}{55} \\\\\frac{63}{55}[/tex]
