Lesson Summary:

In this lesson, we learn how to graph a parabola and state all of its important components, such as the axis of symmetry, vertex point, maximum or minimum point, y-intercept, x-intercepts, domain, and range. By plugging in different values for x, we can determine the corresponding y values and plot the points on the graph. With practice, we can become proficient in graphing quadratic functions and interpreting their properties.

    In this lesson, you will learn to take a quadratic equation in standard form and find the axis of symmetry, vertex point, max / min value, x-intercepts, y-intercept, domain, range, and determine whether the parabola will open up or down and be steep or wide. All steps required to determine these characteristics of the graph are shown and explained.
