|dw:1339145392147:dw| So the graph looks like this: ^ The shaded is the feasibility region. Dos that point count as a corner point?

Does it continue like you shaded in the third drawing? Or is the y-axis the limit of the shaded portion?

5. aroub

The third drawing

6. Chris9k

Then that is not a corner point from my understanding. From that drawing you only have 1 corner point. the bottom one. Unless your actually drawing is completed up higher.

7. aroub

Why it's not a corner point?

8. Chris9k

Because the axis is not a place where the shaded part of your graph stops. The axis is just a reference line to let you know where 0 is.

As you can see in the picture..the 3 points i pointed out are corner points..but where it crosses the x or y axis are not corner points that you would need to check for max/min. Make sense?

Yup it does!! Thank you so much =D
