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