Question

Find the maximum and minimum values of 2x² -15 x² +36x+12​

Answer 1

Answer:

Correct option is

D

54

f(x)=2x

3

−3x

2

−36x+10

f

′

(x)=6x

2

−6x−36

For maxima or minima,

f

′

(x)=0

⇒x=3,−2

f

′′

(x)=12x−6

f

′′

(3)=30>0 and f

′′

(−2)=−30<0

Hence f(x) has a maximum at x=−2

f(−2)=54
