A woodworker makes wooden checkerboards. Her profit is a function of the price she charges. This graph shows her total profits, y, based on the sales price, x, of each checkerboard.
Identify any zeros of the function, and interpret what the zeros mean in terms of the situation.



A. Zeros: x = 15 and x = 70. These are the prices at which she neither makes nor loses money.
• B. Zero: y = 1512.5. This is the maximum amount of profit she can make.
• C. Zeros: x= 15 and x= 70. These are the prices at which she makes the least and greatest amounts of profit.
• D. Zero: x = 42.5. This is the selling price that will give her the greatest profit.
