In this lesson on Parabolas, the focus is on graphing functions in the form of f of x equals a x squared. The lesson covers five different parabolas and their corresponding graphs. It is explained that if the coefficient a is greater than 0, the parabola opens up, and if it is less than 0, it opens down. Additionally, if the absolute value of a is greater than 1, the parabola is steeper, and if it is less than 1, it is wider. The axis of symmetry is the y-axis, and the vertex for all parabolas in this form is at (0, 0). This lesson is a great introduction for those looking to understand the basics of graphing parabolas.
