Solve.The bar graph shows 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.M = -23x3 + 1170x2 - 13,808x + 72,566W = 8x3 - 56x2 + 511x + 14,763Find a mathematical model for M - W and use it to calculate the difference in the median annual income between men and women with 14 years of education. Does the model underestimate or overestimate the actual difference?
