Some football field surfaces in the United States are higher in the center than at the sides, as represented in the figure above, so that water drains from the field. The height difference, f(x), in feet, between the left side and a point x feet from the left side is represented by the function f(x) = -0.00026(x - 80) 2 + 1.666. In the xy-plane, which of the following is the best interpretation of J(40) = 1.25 in this context?
