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.

Basic concepts: Graphing linear functions using table of values, Graphing linear functions using x- and y-intercepts, Graphing linear functions using various forms, Introduction to quadratic functions,

Related concepts: Solving quadratic equations by completing the square, Radian measure and arc length, System of linear-quadratic equations, System of quadratic-quadratic equations,

- 1.$y = 2{\left( {x - 3} \right)^2} - 8$ is a quadratic function in vertex form.a)Determine:

• y-intercept

• x-intercepts

• vertex

b)Sketch the graph.
