This tutorial shows 3 examples of {from factored form y = (x - r)(x - s)} finding the x-intercepts, the vertex and then drawing a sketch of the parabola.

This tutorial shows how to determine features of a parabola's graph: vertex, max or min, value it occurs for, intercepts and axis of symmetry. An example also shows how to model quadratic data using the online calculator at www.desmos.com.

This tutorial shows how to graph parabolas in vertex form using the step method.

This tutorial using Desmos shows how horizontal and vertical translations work for a parabola.

This tutorial demonstrates using a Desmos graph how vertical stretches and compressions work for a parabola.

This tutorial shows how to graph y = x² using a table of values.

This tutorial shows how to graph a quadratic relation using a table of values. Some basic properties of quadratics are covered such as max or min points, the vertex, axis of symmetry and determining if a relation is linear or quadratic using finite differences.

This tutorial shows how to solve quadratic relation applications graphically.
