In this first lecture on the Quadratic Functions and Inequalities series, Dr. Eaton begins with an overview of Graphing Quadratic Functions. She covers what exactly are quadratic functions as well as properties of parabolas such as the axis of symmetry and vertex. She moves into minimum and maximum values and how to determine them. Lastly, she finishes with four examples that test your understanding of the new concepts.
Use the axis of symmetry to help you graph a parabola. Graph the right or left half and then reflect the graph across the axis of symmetry.
The maximum or minimum value of the function occurs at the vertex. Use the formula for the vertex to find the maximum or minimum.
