Intercept form for parabola

Answer 1

y = a(x-p)(x-q)

The x intercepts of this function are (p,0) and (q,0)

This form can be derived by factoring the standard form y = ax2 + bx + c or the vertex form y = a(x-h)2 + k

Answer 2

Oh honey, the intercept form for a parabola is just a fancy way of saying the equation looks like y = a(x - h)(x - k). The (h, k) represents the coordinates of the vertex, and the 'a' is the same 'a' you see in vertex form - it just tells you if the parabola opens up or down. So there you have it, intercept form in a nutshell. Hope that clears things up for ya!
