Step 1

We can start by filling the table. For x=-2, we can calculate for the y-coordinate by substituting x with -2 into the equation:
Hence, we can fill the table as shown:

Step 2

Similarly for x=1, we can calculate for the y-coordinate by substituting x with 1 into the equation:
Hence, we can fill the table as shown:

Step 3

Again, for x=2, we can calculate for the y-coordinate by substituting x with 2 into the equation:
Hence, we can fill the table as shown:

Step 4

Now, we have a table filled with the following coordinates:
Hence, we can plot the points as shown:
 

Step 5

By drawing a curve to join these points together, we get the graph of,
y = x² -2x -3.
