The function f(x) = −x2 − 4x + 5 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 hits the water 1 foot away horizontally from the board x = 1; the diver jumps in the pool at 1 foot per second x = 5; the diver hits the water 5 feet horizontally from the board x = 5; the diver jumps in the pool at 5 feet per second

The answer is the first option, which is: the diver hits the water away horizontally from the board.

The explanation for this problem is shown below:

1. You have the following quadratic equation given in the problem above:

3. To find the zeros, you can factor the quadratic function,as following:

4. You must take the positive value of , which is the horizontal distance from the board to the surface of the pool hitted by the diver.

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
