You can put this solution on YOUR website!
The domains are the set of all real numbers for .... only the meaningful question. You have no or show no definition for the functions, G or F. ONLY the first question can be answered.

%28f%2Ag%29%28x%29=%28x-7%29%28abs%28x%2B7%29%29

The critical x values is at 7.

For x%3E=-7:
%28x-7%29%28x%2B7%29
highlight%28x%5E2-49%29

For x%3C-7:
%28x-7%29%28-1%29%28x%2B7%29
highlight%28-x%5E2%2B49%29
