I don't understand this question

Answer 1

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

`y = x^2-2x+1`

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.
