Precalc Help Pls I Am Stuck On This One So Pls Help class=

Sagot :

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.
