Awoodworker make wooden checkerboards. her profit is a function of the price she chargers. this graph shows her total profits, y, based on the sale price, x, of each check board.

identify any zeros of the function, and interpret what the zeros mean in terms of the situation.

We want to analyze the profit graph and see what the zeros of the function mean. We will see that the correct option is B.

So, the zero of a function is the x-value such that the function is equal to zero.

So, if we have:

y = p(x)

Where y is the profit and x is the sale price of each checkboard, we will have that the zeros are the values of x such that:

y = p(x) = 0

Then the zeros are the values of x such that the profit is equal to zero. A profit of zero means that she does not win nor lose anything, so the correct option is B.

"The zeros at x = 10 and x = 60 are the prices at which she neither makes nor loses money".
