In this lesson, we learn about the two basic forms of a parabola, and how to find the vertex and axis of symmetry using a formula. We apply this to graphing a function in the form of f(x) = ax^2 + bx + c, where we use the formula x = -b/2a to find the axis of symmetry and the vertex as (h,k). We also learn that the value of a determines whether the parabola opens upward or downward, and the steepness of the curve. This lesson provides a good foundation for understanding and graphing parabolas.
