Answer:


Explanation:

The best way to do this is to let a graphing program do it. You could do it from a chart, but a graphing program can be useful for that as well. We'll make up a mini chart here

x method y

-3 (-3)^2 + 2(-3) + 3 = 6

-2 (-2)^2 + 2(-2) + 3 = 3

-1 (-1)^2 + 2(-1) + 3 = 2

0 3

1 (1)^2 + 2(1) + 3 6

2 (2^2) + 2(2) + 3 11

3 (3)^2 +2(3) + 3 18

See the graph below.

You can pick it out from the graphs you were given.
