Quadratic Graph

The general form of a quadratic is \[y = ax^2 + bx + c\]

Using the link below, you can explore some key features of quadratic graphs including:

• Roots, the y-intercept and the line of symmetry
• The family of quadratics of the form \(y = ax^2\) 
• The family of quadratics of the form \(y = x^2 + bx\)
• The family of quadratics of the form \(y = x^2 + c\)
• The completed square form \(y = a(x+p)^2 + q\) (as shown)
