After linear and exponential functions (you'll practice with exponential functions if you continue with algebra) quadratic functions are probably the third most common applied function. Today's lesson introduces you to the vocabulary for quadratic functions and shows you how use the vertex and the intercepts to graph a quadratic function. This material is covered on pages 327 through 338 in the Engaging Algebra textbook.
7.4 Quadratic Functions in Standard Form
After completing this lesson you'll be able to describe, and graph, a quadratic function.
