Please give a mathematical explanation of the signs(positive or negative) of beta1, beta2, and beta3.

We estimate the following regression model to predict wage of employees in a firm. Exp is years of
experience, male is a dummy variable that equals 1 if the employee is male.
wage = Bo + B1exp + B2male + Bzexp × male
If the true relationship between the variables are as the following plot suggests, what do you expect
the signs (positive or negative) of B1, B2, and B3 to be? Explain.
wage 4
male=1
male=0
