Question

Find the maximum and minimum values by evaluating the equation (picture) at the critical points when the restrictions are as follows: (picture)

Answer 1

C min= -5

C max - 0.5

Explanation:

Answer 2

for x=2, y< or equal 6

for y=3, x< or equal 5

minimum : x min= 2 , y max=6, C min= 2/2 -6 = 1-6⇒ Cmin= -5

maximum : x max= 5, y min =3, C max= 5/2 - 3= 2.5-3 ⇒ C max= - 0.5
