Answer:
x not equal to 7
Step-by-step explanation:
(f ° g)(x)
= f (g(x))
So you are scrunching up the entire g(x) function and stuffing it into the x in the f(x).
This gives you
4/|x-7| see image.
x cannot be 7, bc if x is 7 the denominator would be 0 and that's never allowed. So the domain must be restricted and x not equal to 7.
