How do I graph the equation y = x^2-x-6 ?
Thank you very much.

y-intercept:
Let x = 0, then y = 0-0-6 = -6
gives you the point (0,-6)
------
x-intercepts:
Solve x^2-x-6 = 0
Factor:
(x-3)(x+2) = 0
x = 3 or x = -2
-----------------------
Gives you points: (3,0) and (-2,0)

Plot those three points and sketch a parabola opening up through them.
