Hello candidate,

Because of limiting answering modes available on this platform, I am not able to provide you with the mathematical calculation for this problem but I can surely help you with the steps you need to follow to solve out such questions-

1. First of all you need to find out the first derivative of the curve provided

2. Now you need to find out the second derivative in the same manner as we calculated the first derivative.

3. Now equate the second derivative equal to zero, and find out the values of y and later X by putting it in the min question.

Hope this was helpful!!
