Parabola
Designing Parabolas of the form: y=a(x+m)(x+n).
When designing these parabolas, you're taking into account the two linear factors that determine the x-intercepts (x+m) and (x+n), and the vertex. Once you've established the x-intercepts, you need to figure out with a-value will give you the correct vertex. To change the m-, n-, and a-values, click and drag the appropriate slider. Or, after clicking on the specific slider, you can use the arrow keys on your keyboard to make it go up or down.
