Express each relation as a table, a graph, and a mapping. Then determine the domain and range. 1. {(0, 0), (-3, 2), (6, 4), (-1, 1)}
2. {(5, 2), (5, 6), (3, -2), (0, -2)
3. {(6, 1), (4, -3), (3, 2), (-1, -3)}
4. {(-1, 3), (3, -6), (-1, -8), (-3, -7)}

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.
