In this lesson on parabolas, the instructor explains how to determine whether a parabola goes up or down based on the coefficient of x squared. They then demonstrate how to find the axis of symmetry using the formula x = -b/2a, or by recognizing that if there is no x term, the axis of symmetry is x = 0. The instructor also explains how to find the vertex point and y-intercept, which are important for graphing the parabola. Through a series of examples, students will learn how to apply these concepts to different parabolic equations.
