Graphing Quadratic Functions using Transformational Form The Transformational Form of the Quadratic Equations is:
2
Graphing Quadratic Functions using Transformational Form The Transformational Form of this Quadratic Equations is: This also provides the following information: Vertex is (-2, 3) Vertical Stretch is 4 The parabola opens upwards and the Axis of Symmetry is
3
The Transformational Form of this Quadratic Equations is: Vertex is (-2, 3) Vertical Stretch is 4 a> 1, so the graph rises faster than it normally does and appears to be skinny! The parabola opens upwards and the axis of Symmetry is
4
Vertex is (-2, 3) Vertical Stretch is 4 Pattern from the vertex is now: Over 1, up 1X4 Over 2, up 4X4, etc
5
Now you try the following: Name the vertex, vertical stretch and then graph. 1. 2. 3. 4. Vertex is (1, 2) VS is 2 Vertex is (-2, 5) VS is Vertex is (5, -4) VS is -3 Vertex is (-4, -6) VS is
6
Using Mapping Rules to Graph Quadratics Vertex is Axis of Symmetry is Horizontal Translation is Vertical Translation is Vertical Stretch is TRANSFORMATIONAL FORM MAPPING RULE
