Find the absolute extrema if they exist, as well as all values of x where they occur, for the function f(x) =x + 4x + 4x - 8 on the domain [ - 4,0] Identify the absolute maximum 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. O A. The absolute maximum is . which occurs at x = (Round the absolute maximum to two decimal places as needed. Type an exact answer for the value of x where the maximum occurs. Use a comma to separate answers as needed.) O B. There is no absolute maximum. 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. O A. 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
