EZ Graph - Parabola, Standard Form

A simple parabola with its vertex at the origin and its curve opening upward can be expressed with this equation:

y = x2

A more complicated equation for a parabola would look like this:

y = a(x - h)2 + k


  • a is the vertical scaling factor.
  • h is the horizontal translation.
  • k is the vertical translation.

This version for the equation of a parabola is often said to be in 'standard form'.
