========================================================
Explanation:
The domain of
is the same as the domain of g(x)
The domain for g(x) is
saying we can plug in any number we want as long as it's not 13. This is to avoid dividing by zero. The same domain applies for the composite function because

and we can see that we still need to kick out x = 13 from the domain to avoid the division by zero issue.
Answer:
She will exercise for 6 hours in four weeks.
Step-by-step explanation:
Summer exercises for 0.5 hour on Monday, 0.5 hour on Wednesday, and 0.5 hour on Friday. There are 3 days where she exercises for 0.5 hour.
3 days X 0.5h = 1.5h each week
For four weeks, multiply the hours each week by 4.
1.5h X 4 weeks = 6h
Therefore Summer will exercise for 6 hours over the course of 4 weeks.
