For 1 and 2, use integer values of x from -3 to 3 to graph the equation(1)      y = -2x2 + 3         (2x squared)                                   abcd

This would be an upside down parabola with a vertex at (0, 3).

To complete the chart, just plug x into the equation and evaluate.

Here is the completed table:

x      y
-3    -15
-2    -5
-1    1
0     3
1     1
2     -5
3     -15
