Question

find the zeros of f(x)=X^2+X-6

Answer 1

2 and -3

Answer 2

"Zeros" of a function are x (input) values for which the function itself is zero.

So, you're trying to find solutions to \[x ^{2}+x-6=0.\]
There are various ways to solve this equation for x, including (but not limited to):
1) graphing
2) quadratic formula
3) factoring
4) factoring by grouping
5) synthetic division

Any of these look familiar to you? If so, start with the one you think is easiest.

Answer 3

THANK YOU SO MUCH! Can you please help me with a word problem now?

Answer 4

A baseball player hits a ball toward the outfield. The height h of the ball in feet is modeled by h(t) = -16t2 + 22t + 3, where t is the time in seconds. In addition, the function d(t) = 85t models the horizontal distance d traveled by the ball. If no one catches the ball, how long will it stay in the air? (Round to the nearest tenth of a second and enter only the number.)

Answer 5

I'd love to. But I've already committed to helping another student, and that could take a while. Either re-post your homework problem now and wait to see who responds (I might be able to do that later on), or post it later.

Answer 6

okay, thank you either way! I hope you'll get to me when you have time
