Formula used: To find absolute maximum and minimum of a function, 1. Set the first derivative of the function to zero, f' (a)= 0, to find the critical values of the function 2. Substitute the critical values intof (x) 3. Substitute the end points into f (x) The maximum value is absolute maximum and the minimum value is absolute minimum

f' (x) 6x 6x - 12 6x2 - x - 2) Now, set f'(x) 0 6(x2 x 2) = 0 6(x2 2x x- 2) 0 6(x(x 2)1x 2)) 0 6(x 1)(x 2) = 0 Thus, either x +1 0 or x - 2 0.
