Graphing Quadratics in Standard Form

The video tutorial explains how to graph quadratic functions in standard form using the OMG math method. It covers finding the vertex using the formula -B/2A, plotting points on an XY plane, and understanding the symmetry of quadratic graphs. The tutorial provides step-by-step instructions for calculating Y-values and graphing the function, concluding with additional resources for further learning.

Which formula is used to find the vertex's x-coordinate of a quadratic function in standard form?

• A / 2b

• B / 2a

• -B / 2a

• -C / 2a

What values are chosen around the vertex's x-coordinate for plotting additional points?
