Correct me if I am wrong 0 votes 0 votes Pratikumar commented Dec 29, 2023 reply Follow Share Hi, Naveen you are right regarding stationary point…….. but [-1,1] will be slightly wrong because at x=-1, x=1 dy/dx does not exist so I think correct answer for stationary points would be (-1,1) 0 votes 0 votes Please log in or register to add a comment.
