Thank you for the opportunity to help you with your question! Hope your day is going well!

There are three cases for this problem

You have to find the domain

|4-x| greater than or equal to zero

x> or equal 4

|x/2+7| great than or equal to zero


x greater than or equal to 14

Case 1






Case 2





This is not the domain

Case 3






Therefore our points are -2, and -6.

I'm sorry, I am slightly wrong. I did a check on my answer. Our points are x=-2, and 22

Ignore the third case, and my reasoning why 22 is not in there. I logically thought that wrong slightly.
