Jen and her friends would like a curved pit to be included in next year’s obstacle course. They found this equation to model their suggested curved pit using a computer simulation. In the equation, y is the depth of the pit in relation to the surface of the course, and x is the horizontal distance from the left edge of the entire obstacle course. Both distances are in feet. y = 0.75x^2 − 13.5x + 57.75

Select the correct answer from each drop-down menu.

A robot traveling along the surface of the curved pit reaches a (maximum, minimum, or contrast) depth of (-3, -9, 4, or -7) feet.
