Question

What point in the feasible region maximizes the objective function?

Answer 1

i tried to do it but i think the question is mising a constraint

Answer 2

what's the objective function?

Answer 3

Objective function: C=5x—4y

Answer 4

If you draw the inequality plot, you should get 4 potential critical points; (0,0); (0,1); (1.5,1.5); (0,3)

Plug each one into the objective function and see which one gives you the largest number?

You should get the maximum of the objective function to be 1.5.

Answer 5

i dont get it i drew the graph but i dont undestand it

Answer 6

When you draw the graph, there if should be a 4 sided shape and hence have four corners. What are the coordinates of the 4 points?

Answer 7

yah my graoh looks weird
i used this website http://my.hrw.com/math06_07/nsmedia/tools/Graph_Calculator/graphCalc.html
and in the first y i put -x+3 and for the second y i put 1/3+1

Your shape should look like this.

Answer 9

oh ok i was reading th graph wrong we got the same answer

Answer 10

So what point (x,y) maximises the objective function?

Answer 11

(1.5,1.5)

Answer 12

Yep, great stuff.
