Question

The function f(x) = -x2 - 5x + 50 shows the relationship between the vertical distance of a diver from a pool's surface f(x), in feet, and the horizontal distance x, in feet, of a diver from the diving board. What is a zero of f(x) and what does it represent?

a.) x = 5; the diver jumps in the pool at 5 feet per second

b.) x = 10; the diver jumps in the pool at 10 feet per second

c.) x = 10; the diver hits the water 10 feet horizontally from the board
