The general equation of a parabola is: y = a(x-h)2 + k or x = a(y-k)2 +h, where (h,k) denotes the vertex. The standard equation of a regular parabola is y2 = 4ax.Some of the important terms below are helpful to understand the features and parts of a parabola y2 = 4ax...
The x-coordinate of the vertex can be found by the formula−b2a−b2a, and to get the y value of the vertex, just substitute−b2a−b2a, into the the equqation as shown in the diagram and example below: Finding Vertex from Vertex Form ...
The equation of a vertical parabola is often seen in vertex form, or {eq}y = a(x-h)^2 + k {/eq}. In this form, the vertex is at (h, k) and the focus is at (h, k + {eq}\frac{1}{4a} {/eq}). Notice that the x-coordinate is the same for both the vertex and focu...

I did this because the formula for the vertex form is: y= a(x−h)2+k I wanted to make very clear to myself that the value that was subtracted fromxto result in the binomialwas a negative value. Because, to get a "plus" in the simplified form, I had to have subtracted a "mi...
