What is the Objective Function and Constraints for this Optimization Problem?

[Roni1985]

Homework Statement

Optimization (Maximize or Minimize)
JJCJ=-x +2y according to:
A(1,2)
B(-1,2)
C(-1,-3)

Homework Equations

The Attempt at a Solution

I have taken many advanced math courses and its kind of embarrassing that I don't know how to approach this question :\
First I thought there was a mistake with the question but my cousin says that this is what the professor game them. I don't even know what JJCJ is...
Would appreciate any help.

C(-1,-3)

This doesn't make any sense to me, especially the part "... according to A(1, 2), B(-1, 2), C(-1, -3).

A, B, and C are points.

In optimization problems you are usually given some objective function (like your JJCJ above - I have no idea what JJCJ means), and the constraints are inequalities, such as x >= 0, y >= 0, 2x + 3y <= 5.

Do the points in your problem constitute vertices in the critical region?

What is the exact wording of the problem?

That's what I thought... the problem doesn't make sense. And, this is the exact wording that the professor gave to the students. I'll ask my cousin to contact the professor.

Thanks for your help.
