M00 2 .015x2 +1.31): YB, 30 5x 560. represents the miles per gallon obtained at a speed ofx miles per hour. (3) Find the absolute maximum miles per gallon and the speed at which it occurs. (b) Find the absolute minimum miles per gallon and the speed at which it occurs. For a certain automobile. M(x) : .015x2 +1.23): 7.9, 30 s x $60. represents the miles per gallon obtained at a speed of 3: miles per hour. (3) Find the absolute maximum miles per gallon and the speed at which it occurs. (b) Find the absolute minimum miles per gallon and the speed at which it occurs. (a) The absolute maximum miles per gallon is . This occurs at mph. (Type an integer or decimal rounded to the nearest thousandth as needed.) Find the open intervals where the function f(x) = 19x - 19 e "*is concave upward or concave downward. Find any inflection points. Select the correct choice below and fill in any answer boxes within your choice. O A. The function has a point of inflection at (Type an ordered pair. Use a comma to separate answers as needed. Use integers or fractions for any numbers in the expression.) B. The function does not have an inflection point. Select the correct choice below and fill in any answer boxes within your choice. O A. The function is concave upward on the interval(s) and concave downward on the interval(s) (Type your answers in interval notation. Use a comma to separate answers as needed.) O B. The function is concave upward on the interval(s) The function is never concave downward. (Type your answer in interval notation. Use a comma to separate answers as needed.) O C. The function is concave downward on the interval(s) The function is never concave upward. (Type your answer in interval notation. Use a comma to separate answers as needed.) O D. The function is never concave upward or downward.Find the absolute extrema if they exist, as well as all values of x where they occur, for the function f(x) = x# - 98x- + 1 on the domain [ - 8,8].
