Find x-and y-Intercepts From Graphs

[nycmathguy]

NOTE:

I WILL NOT VERIFY MY RESULTS ALGEBRAICALLY. I HAVE BEEN DOING SO ALL WEEK LONG.

Question 19

y-intercept is 9.

x-intercept is 3.

Question 20

y-intercept is 16.

x-intercepts are -2 and 2.

Question 21

y-intercept is 2.

x-intercept is -2.

Question 22

y-intercepts are 2 and -2.

x-intercept is 4.

Note: Back to Calculus on Friday through the weekend.
