Find the absolute maximum and minimum values of the function over the indicated interval, and indicate the xvalues at which they occur. f(x) = 6 +2x2x2; [0,4] 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 at x = . (Round to two decimal places as needed. Use a comma to separate answers as needed.) f(x) 9,0 Find a) any critical values and b) any relative extrema. Ne)\" Question f(x)=x2+4x+9 a) Select the correct choice below and, if necessary, fill in the answer box within your choice. O A- The critical value(s) of the function is/are . (Use a comma to separate answers as needed.) O B. The function has no critical values. b) Select the correct choice below and, if necessary, ll in the answer box(es) within your choice. O A- The relative minimum point(s) is/are and there are no relative maximum points. (Simplify your answer. Type an ordered pair, using integers or fractions. Use a comma to separate answers as needed.) O B- The relative maximum point(s) is/are and there are no relative minimum points. (Simplify your answer. Type an ordered pair, using integers or fractions. Use a comma to separate answers as needed.) O C. The relative minimum point(s) is/are and the relative maximum point(s) is/are . (Simplify your answers. Type ordered pairs, using integers or fractions. Use a comma to separate answers as needed.) O D. There are no relative minimum points and there are no relative maximum points
