Answer 10

When you understand what a root is, you will be able to do this problem. A root is the x value that corresponds to a y value of 0

Answer 11

Another way to say it is: a root is the point where the graph crosses the x axis.

Answer 12

Some people say, "a root is an x intercept"

Answer 13

Oh ok

Answer 14

So you need to look at your points and it you were drawing the graph...where would it cross the x axis? There are 2 places.

Answer 15

-1 to 0
-2 to -1
