Lesson: Recognizing Features of Quadratic Functions from Their Graphs

In this lesson, we will learn how to use the features of a quadratic function to graph it by finding the y-intercept, the equation of the axis of symmetry, the vertex, and the minimum or maximum value, and then state the domain and range of the function.
