The absolute maximum of on the interval is
Explanation for the correct option :
Step-1 : Finding the critical points of
To find the critical points of , we have to differentiate and then equate it to zero.
Differentiating with respect to , we get
Now, the critical points of will be the solutions of . Then
Step-3 : Fining the maximum value of
Substituting , we get
Substituting , we get
Thus, the absolute maximum value is .
Hence, option (B) is the correct answer.
