Find the points at which the function f (x) = > has a maximum or a minimum value in the interval [-1, 2]. O A. absolute minimum at (0, 0); no maxima O B. absolute minimum at (0, 0); absolute maximum at ( 2, v/4) O C. no minima; local maximum at (-1, 1) and absolute maximum at (2, v/4) O D. absolute minimum at (-1, 1); absolute maximum at ( 2, v/4) O E. absolute minimum at (0, 0); local maximum at (-1, 1) and absolute maximum at (2, /4)
