In order to do plot this graph, you should draw a table with x values -2, -1, 0, 1, 2 and then substitute in each x value into the equation. this will provide you with y values. once you have this, you can use the y value for each x value as coordinates and plot them on a graph. For example, when X=0, y= (0)^2 - 3, therefore y= -3. This gives a coordinate of 0, -3, which you can plot on a graph.... more

Substitute the values of x into the equation

For x =-2, y = (-2)^2 - 3 = 1

For x =-1, y = (-1)^2 - 3 = -2

For x =0, y = (0)^2 - 3 = -3

For x =-2, y = (-1)^2 - 3 = -2

For x =2, y = (2)^2 - 3 = 1

Your co-ordinates will be as follows:

(-2,1) (-1,-2) (0,-3) (1,-2) (2,1)

Join these points together to form your graph
