The best way to interpret polynomial regressions is to

Under the least squares assumptions for the multiple regression model (zero conditional mean for the error term, all Xi and Yi being i.i.d., all Xi and ui having finite fourth moments, no perfect multicollinearity), the OLS estimators for the slopes and intercept (check all that apply):

In the regression model    Yi  = B0 + B1 Xi + B2 Di + B3 (Xi * Di) + Ui where Y is the earnings in dollars, X is year of education and D is a binary variable (=1 for female and =0 for male),  β3
