The function
f(x)=βˆ’x2βˆ’7x+30
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 = 10; the diver hits the water 10 feet away horizontally from the board.

b) x = 3; the diver hits the water 3 feet away horizontally from the board.

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

d) x = 3; the diver jumps in the pool at 3 feet per second.
