Consider the two inequalities 2x  4 < y and y < 2/3x + 2.
(b) Graph the region of the plane that satisifies either inequality, or both inequalities.
(c) Graph the region of the plane that satisifies either inequality, but NOT both.
What I don't get is that in another question, (a), not shown, it says to graph the region of the plane which satisfies both inequalities. Isn't that the same as (b)?
I also don't know how to find/do c.
Thanks!

No, not the same. Either or both is not the same as both.
c) in C, exclude the area that includes both.
