Answer:

  48

Step-by-step explanation:

Evaluate each of the functions by putting the number where x is.

  $g(x)=x^2-4\\\\g(-7)=(-7)^2-4=49-4\\\\\boxed{g(-7)=45}\\\\f(x)=x+4\\\\f(-7)=-7+4\\\\\boxed{f(-7)=-3}$

Then the difference is ...

  g(-7) -f(-7) = 45 -(-3) = 45 +3 = 48

Answer 2

Answer:

solution given;

g(x)=x²-4

f(x)=x+4

Now

g(-7)-f(-7)=(-7)²-4-(-7+4)=49-4+3=48

48 is a required answer.
