I'm new here so bare with me. Also, if you can help me figure out how to do this for future problems it would be greatly appretiated

The feasible region determined by a system of constraints is given. Find the minimum and maximum values of the objective function for the given region.

C = 3x + 4y

Now is a graph with the points:

(-1,0)

(1,3)

(3,2)

(4,0)
