How to graph parabolas for quadratic functions

Now Playing:Quadratic function in general form– Example 1

Graphing Quadratic Functions in General Form
$y = 2{x^2} - 12x + 10$ is a quadratic function in general form.
1. Determine:
  • y-intercept
  • x-intercepts
  • vertex
2. Sketch the graph.
Graphing Quadratic Functions in Vertex Form
$y = 2{\left( {x - 3} \right)^2} - 8$ is a quadratic function in vertex form.
1. Determine:
  • y-intercept
  • x-intercepts
  • vertex
2. Sketch the graph.
