About This Lesson
http://www.freemathvideos.com In this math tutorial I will show you how to sketch a quadratic function, find the axis of symmetry, determine the y-intercepts and find the zeros or x-intercepts. To find the x-intercepts we use such methods as setting the equation equal to zero and factor, completing the square or using the square root method. For the y-intercept we set x=0 and solve for f(x). The vertex and axis of symmetry can be found by converting the equation from standard form to vertex form by completing the square. http://www.freemathvideos.com presents: Learn math your way.
