Quadratic function in vertex form: y = a(x-p)^2 + q
y=2(x−3)2−8 is a quadratic function in vertex form.
Sketch the graph.
Besides the general form, the vertex form is also another way to express a quadratic function. In this lesson, we will talk about how to find the x-intercepts, y-intercepts, vertex of quadratic functions in vertex form.
