Solve.A census was taken to determine the median annual income for residents of a selected region of the United States, by level of education. The given polynomial models describe the median annual income for men, M, and for women, W, who have completed x years of education. Shown in a rectangular coordinate system are the graphs of the polynomial models. Identify the median annual income for a man with 20 years of education as a point on the appropriate graph.M = 224x2 - 1266x + 20,106W = 287x2 - 4030x + 33,761
