## anonymous one year ago If F(x) = x + 4 and G(y) =, what is the domain of G(F(x))? A. x -4 B. All real numbers. C. x 4 D. All real numbers except -4

1. anonymous

depends a lot on what $$G$$ is

2. anonymous

g(y)= 1/y

3. anonymous

then $g(y)=G(x+4)=\frac{1}{x+4}$

4. anonymous

you cannot divide by zero (you will explode) solve $x+4=0$ for $$x$$

5. anonymous

I think it's D

6. anonymous

It is D!! THANK U!!!
