What is the procedure for locating absolute maximum and minimum values on a closed bounded domain R? Select the correct choice below. A. Determine the values of the function at all critical points of R. The greatest of these values is the absolute maximum on R, and the least of these is the absolute minimum. B. Determine the values of the function at all critical points in R. Then find the maximum and minimum values on the boundary of R. The greatest of these values is the absolute maximum on R, and the least of these is the absolute minimum. C. Because the absolute extreme values always occur on the boundary, find the maximum and minimum values of the function on the boundary of R. D. A continuous function on a closed bounded domain may not have absolute extreme values.

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
