How do you graph a quadratic equation into a parabola?
For example: y=x^2+4x+3
---------------------------------
Plot a few points and draw a curved line thru them.
If x=0,y = 3
If x=1, y = 8
If x=-1, y = 0
If x=-2, y = -1
etc.

Pick values for x and find y.
Plot the points, draw a curve thru them.
Same as any other graph.
