You were on the right track with the first -1 you've filled out.
The x column should continue counting up to 4.
For each x value in the table, plug it into the equation
[tex]y = x^2-2x+1[/tex]
And return the y value that you get.
When finished, the y column will have the values:
9, 4, 1, 0, 1, 4, 9
Then, write out the x and y values in point form (x,y). You're only copying what you have down in the table already. It will look like:
(-2, 9), (-1, 4), (0, 1), ... etc.
Then plot the graph.
