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

Answer 2

Did you plug 0 for f(x) and try to solve for x?

Answer 3

Ya, and i got 1 and -10

Answer 4

Ok.
Well we can get rid of A and B because x represents the horizontal distance from the diving board

Answer 5

ok. and?

Answer 6

hello.? @nikato ?

Answer 7

Should be C
By process of elimination.
Can't be D because you said u got -10 but the answer said 10
