# Graphing quadratic functions: General form VS. Vertex form

### Graphing quadratic functions: General form VS. Vertex form

In this lesson, Dennis will show us how to look for the y-intercept, x-intercept and vertex of a parabola from its general form and then sketch the parabola.

#### Lessons

• 1.
Graphing Quadratic Functions in General Form
$y = 2{x^2} - 12x + 10$ is a quadratic function in general form.
a)
Determine:
• y-intercept
• x-intercepts
• vertex

b)
Sketch the graph.

• 2.
Graphing Quadratic Functions in Vertex Form
$y = 2{\left( {x - 3} \right)^2} - 8$ is a quadratic function in vertex form.
a)
Determine:
• y-intercept
• x-intercepts
• vertex

b)
Sketch the graph.
