Here we need to check all the values including 0 to 3 that at which value max occurs. Critical or stationary points(1,2) doesn't give the maximum but at 3 we get the maximum value of 6. f(0) = -3 f(1) = 2 f(2) = 1 f(3) = 6 0 votes 0 votes LeenSharma commented Jan 9, 2018 reply Follow Share In the given interval at the x=3 function will maximum value (6). 0 votes 0 votes pradeepchaudhary commented Jan 3, 2019 i moved by Lakshman Bhaiya Jan 3, 2019 reply Follow Share answer is 6 ,which is at x=3 0 votes 0 votes Please log in or register to add a comment.
