Consider the two inequalities 2x - 4 < y and y < -2/3x + 2.

Question

(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!

Answer 1

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