You are correct.

jimthompson5910 (jim_thompson5910):

You solve x-9 >= 0 to get x >= 9 which leads to [9, inf)

Awesome!! thank you! i have another question like this, hold on i will attach it

jimthompson5910 (jim_thompson5910):

good, you can't divide by zero and that only happens when x = 4

jimthompson5910 (jim_thompson5910):

so you kick out x = 4 from the domain (every other real number is in the domain)

OpenStudy (anonymous):

oh, so it is C?

jimthompson5910 (jim_thompson5910):

no I was agreeing with your answer

jimthompson5910 (jim_thompson5910):

you start with (-inf, inf) but you have to exclude x = 4 which leads to D
