either by using a graphing calculator, or by making a two columned table, on one side, label it X and number it from -4 to 4 and on the other column, label it Y and make it the cooresponding x number squared. graph these points and connect the dots, not with straight lines, but with a smooth curve

You can use a simple graphing program, downloadable from the Internet, or get a graph paper and a calculator and draw some tables of values relating y=x^2. Whatever method you use, you should get a U-shaped curve (mathematically known as a parabola), with the y-intercept being 0. The line of symmetry of the curve is y=0.

You could use a calculator, or you could create a table of values for y versus x and then plotting them on graph paper.
Whe n x =0, y=1; When x =+/- 1, y=1; When x=+/- 2, y = 4,etc

Plug and chug.
Put in numbers for X, figure out what Y is,
then plot those points.
x y
-2 4
-1 1
0 0
1 1
2 4
3 9

you can use MS excel to do this, too
column A1 x
column B1 x*x
Left click on cell A2 and enter the value 1
Left click on cell B2 and enter the Excel formula =A2*A2
fill some values of x in A2, A3, ...., A10
Select A1 .. B10
Click Chart Wizard
Left click on XY(Scatter) and then the last graph to give a scatter
then Click Finish

pick some values of "x" and solve for "y".....
use -4, -3, -2, -1, 0, 1,2,3,4
the resulting graph is the base parabola with vertex (0,0)
