Question

Use the functions f(x) and g(x) to answer the question. F(x)=x²-16; g(x)=x+4

Which answer is equal to (f/g)(x)

A x+4,x=-4
B x+4,x=4
C x-4,x=4
D x-4,x=-4

**All eqaul signs in answers are "do not equal signs"**

Answer 1

(x^2) - 16 / x+4 = (x-4)(x+4) / (x+4) = x-4, x not equal to -4

D is the answer.
