Videos, worksheets, games and activities to help Algebra students learn how to graph parabolas that are written in the vertex form, y = a(x - h)

The vertex form of a parabola is y = a(x - h)

Given the vertex form y = a(x - h)

1. Plot the vertex (h, k)

2. If a > 0 then (h, k) is the minimum point, if a < 0 then (h, k) is the maximum point.

3. Substitute x = 0, to get the y-intercept

4. Substitute y = 0, to get the x-intercept

Short cut method:

Given a parabola, y = ax

1. Calculate \(h = - \frac{b}{{2a}},k = f\left( { - \frac{b}{{2a}}} \right)\)

2. Rewrite the equation as y = a(x - h)
