Answer:
A
Step-by-step explanation:
A function composition is where one function is substituted within another function and is written g(f(x)). Here we will substitute f(x) into g(x). For g(f(-7)), we substitute -7 for x.
[tex] \frac{x^2+6+8}{x^2+6}[/tex]
Now substitute -7 for x.
[tex]\frac{x^2+6+8}{x^2+6} = \frac{(-7)^2+6+8}{(-7)^2+6}=\frac{49+6+8}{49+6}=\frac{63}{55}[/tex]
