Understanding Parabolas and Their Graphs

The video tutorial explains how to match equations of parabolas to their corresponding graphs. It covers the transformation of equations into vertex form, determining the vertex, and identifying whether the parabola opens up or down. Each of the six equations is analyzed, and the correct graph is identified based on the vertex and the direction the parabola opens.

What is the standard form of a parabola as mentioned in the video?

• y = ax^2 + bx + c

• y = ax + b

• y = a(x - h)^2 + k

• y = a(x - h)(x - k)
