You can put this solution on YOUR website! Assuming you are not allowed to use a graphing calc or some other tool, you can always do it the old fashioned way.
Make a table with two columns. Label one column x and the other column y.
Pick a value for x and put it the column on row 1. Then square that value and write it's negative in the y column. Pick several other vaues for x and do that same thing.
Now plot those points (x,y) and then draw in the curve that connects them.
