A local shop prints photos. The function f(x) = −x2 + 20x − 75 models the profit from one customer, where x is the number of photos printed.

Determine the zeros, and explain what these values mean in the context of the problem.

x = 5, x = 15; The zeros represent the number of photos printed where no profit is made.
x = 5, x = 15; The zeros represent the number of photos printed to produce a maximum profit.
x = 10, x = 25; The zeros represent the number of photos printed where no profit is made.
x = 10, x = 25; The zeros represent the number of photos printed to produce a maximum profit.
