Question

PLEASE HELP!!!!!!!!!!

The function f(x) = -x^2 - 9x + 10 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?

x = 1; the diver jumps in the pool at 1 foot per second

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

x = 1; the diver hits the water 1 foot away horizontally from the board

x = 10; the diver hits the water 10 feet away horizontally from the board

Answer 1

I think the correct answer from the choices listed above is the third option. The zero of f(x) would be x = 1. Therefore, the diver hits the water 1 foot away horizontally from the board. Hope this answers the question. Have a nice day. Feel free to ask more questions.
