How would the shape of the total supply curve in Solved Problem 2.2 change if the U.S. domestic supply curve hit the vertical axis at a price above p̅?

Problem 2.2

The estimated supply function for avocados is Q = 58 + 15p - 20p_f, where p_f is the price of fertilizer.
Determine how much the supply curve for avocados shifts if the price of fertilizer rises from $0.40 to $1.50 per lb. Illustrate this shift in a diagram.
