Graphing from a Table

Step 3. Substitute x-values from the table into the equation to fill in the y-values.
y = (0 - 2)2 - 3, y = 1
y = (1 - 2)2 - 3, y = -2
y = (3 - 2)2 -3, y = -2
y = (4 - 2)2 - 3, y = 1
x | 0 | 1 | 2 | 3 | 4 |
y | 1 | -2 | -3 | -2 | 1 |
*Note: The table will have symmetrical values on each side of the vertex.
Step 4. Plot the points from the table and sketch the curve.
