Find the absolute extrema if they exist, as well as all values of x where they occur, for the function f(x) =2x" - 8x + 8x +5 on the domain [0,4] Find the derivative of f(x) = 2x3 - 8x2+ 8x + 5. FIX)-6x2- 16x +8 Identify the absolute minimum if it exists, as well as all values of x where it occurs. Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice OA. The absolute minimum is which occurs at x = (Round the absolute minimum to two decimal places as needed. Type an exact answer for the value of x where the minimum occurs. Use a comma to separate answers as needed.) O B. There is no absolute minimum
