Standard and vertex form of the equation of parabola and how it relates ...The vertex form of a parabola's equation is generally expressed as: y = a (x − h) 2 + k. (h,k) is the vertex as you can see in the picture below. If a is positive then the parabola opens upwards like a regular "U". If a is negative, then the graph opens downwards like an upside down "U".
