Staff Review
This lesson extends the ideas learned from the previous lesson and goes through another example of finding all of the characteristics and important values for a parabola in standard form. All steps needed to find these values are shown and explained. The equation is also graphed. Unfortunately, the sound cuts out at the 3-minute mark, but all work is still shown.
