In this lesson, we learn how to graph quadratic functions in the form y = a(x-h)^2+k. By identifying the vertex and axis of symmetry, we can sketch the parabola and determine if it opens up or down, and if it's wider or steeper than the standard parabola y = x^2. The lesson also provides an example problem for students to practice. The video concludes by briefly mentioning that not all quadratic functions will be in this form and introduces the next lesson on graphing quadratic functions in general form.
