Answer:

Explanation:

Domain means all of the x-values for the graph in this case the x's are days. There are no negative number of days since the account was opened so the domain is 0 <= x <= 21. The 21 comes from the fact that the account was open for 3 weeks (that is 21 days)

Range means all the y-values which here the y stands for the balance if the account. The account was never negative according to the graph. And it was stated that the highest balance was $400. So the range is 0 <= y <= 400. Sorry i cant read the next question it is cut off. But maybe you can tell by looking at the image I will attach same with some notes and comments. On day 12 when the balance was 0, written in function notation is f(12)=0

Lastly, section 4 (segment 4) on the graph shows when the balance was zero because the y-values for that piece if the graph is 0
