Answer:
C
Step-by-step explanation:
Okay, so for this, you need to know that (g°f)(x) = g(f(x))
in order words, we are using the f(x) equation as X for the g(x) equation..
[tex]\frac{ x^{2} +5 + 5}{ x^{2} +5}[/tex] = [tex]\frac{x^{2}+10}{x^{2}+5}[/tex]
Now, we just plug in -3 for X
[tex]\frac{(-3)^{2} + 10 }{(-3)^{2} + 5} =\frac{9 + 10}{9 + 5} = \frac{19}{14}[/tex]
