Answer this question

A. 5 B. 3,5

Step-by-step explanation:

A. (h/g)(4) means h(x)/g(x) where x=4, so you would set up the equation as (x-9)/(x-3)*(x-5), then plug in 4 for all your x values.

Doing this you get (4-9)/(4-3)*(4-5), simplifying this you get -5/(1*(-1)=5

B. 3 and 5 are the values not in the domain because when you plug them in for you x values you would get a 0 in the denominator.

For example, when you plug in 3 for x, you get -6/(0*-2)=-6/0

This gives you a 0 in the denominator which you can not do
