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.

What is the shape of the graph for a quadratic function?

• Circle

• U-shape

• Triangle

• Straight line

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

• A / 2b

• B / 2a

• -B / 2a

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

• Random values from the function

• Only values less than the vertex

• Only values greater than the vertex

• Values less than and greater than the vertex

How do you calculate the y-value for a given x-value in the function?

• None of the above

• Subtract x from the vertex

• Multiply x by itself and add coefficients

• Plug x into the quadratic equation
