Introduction to quadratic functions

Now Playing:Quadratic function in general form– Example 1

Identifying Characteristics of Quadratic Functions in General Form: $y = ax^2 +bx + c$

$y = 2{x^2} - 12x + 10$ is a quadratic function in general form.
i) Determine:
• y-intercept
• x-intercepts
• vertex

ii) Sketch the graph
Identifying Characteristics of Quadratic Functions in Vertex Form: $y = a(x-p)^2 + q$

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

ii) Sketch the graph
