Learn how to graph a quadratic

The video tutorial explains how to graph the quadratic function f(x) = x^2 - 8x + 15. It covers determining the axis of symmetry using the formula x = -b/2a, identifying the graph's orientation based on the value of 'a', and finding the vertex. The tutorial also demonstrates creating a table of values to plot points on the graph and using symmetry to complete the graph. The teacher provides step-by-step instructions and tips to make the process easier.

How is the vertex related to the axis of symmetry?

What are the coordinates of the vertex for the function f(x) = x² - 8x + 15?

What points did the teacher suggest to find on either side of the axis of symmetry?
