Answer:
Five plus the difference of seventeen and eight
C is the answer. By only looking at the domain (the stuff on the right in the functions), you can see that the first equation has a hole at x=2, meaning it does not have a value here at x=2. When x<2, there are values for the 1st function. When x>2, there are values for the second function, as well as when x=2
The correct answer is the first option -
ninth root of x squared.
