15. Find the absolute maximum and minimum values of the function over the indicated interval, and indicate the x-values at which they occur. 2 f(x) = (x + 5) # - 1; [- 8,8] The absolute maximum value is 13 at X = - 1 (Round to two decimal places as needed. Use a comma to separate answers as needed.) The absolute minimum value is at X = (Round to two decimal places as needed. Use a comma to separate answers as needed.) 16. Find the absolute maximum and minimum values of the function over the indicated interval, and indicate the x-values at which they occur. f(x) = x + -: [1,20] The absolute maximum value is at x = (Use a comma to separate answers as needed.; The absolute minimum value is atX= (Use a comma to separate answers as needed. 17. Find the absolute maximum and minimum values of the function over the indicated interval, and indicate the x-values at which they occur. 5x f(x) = [-4,4] x2+9 The absolute maximum value is at x = (Round to two decimal places as needed. Use a comma to separate answers as needed.) The absolute minimum value is atx= (Round to two decimal places as needed. Use a comma to separate answers as needed.)19. Find the absolute extrema of the function, if they exist, over the indicated interval. Also indicate the x-value at which each extremum occurs. If no interval is specified, use the real numbers, ( - 00,co). f(x) = Vx; [0,1] Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. O A. The absolute maximum is at x = and the absolute minimum is at x = (Use a comma to separate answers as needed.) O B. The absolute maximum is at x = and there is no absolute minimum. (Use a comma to separate answers as needed.) O C. The absolute minimum is at x = and there is no absolute maximum. (Use a comma to separate answers as needed.) O D. There is no absolute maximum and no absolute minimum. 20.
