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

Topic Notes

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.
