### Graphing quadratic vertex form

1. 1. Graphing Quadratic Equations in Vertex Form<br />
2. 2. Anatomy of a Quadratic Equation in Vertex Form<br />a, h, and k are called “parameters”<br />The vertex is <br />The axis of symmetry is<br />
3. 3. For Example…<br />Axis of Symmetry<br />Vertex<br />
4. 4. y<br />5<br />5<br />x<br />O<br /> 5<br />5<br />Vertex: ______________<br /> <br />Axis of Symmetry: _________<br /> <br />Direction: __________<br /> <br />Root(s): _______ ________<br />up<br />26<br />10<br />0<br />-6<br />-6<br />0<br />10<br />
5. 5. Describe the Transformation<br />Vertical stretch 2, <br />right 4, down 8<br />Write the Equation in Standard Form<br />
6. 6. y<br />5<br />5<br />x<br />O<br /> 5<br />5<br />Vertex: ______________<br /> <br />Axis of Symmetry: _________<br /> <br />Direction: __________<br /> <br />Root(s): _______ ________<br />down<br />-31<br />-5<br />0<br />3<br />3<br />0<br />-5<br />
7. 7. Describe the Transformation<br />Reflect over x-axis, <br />left 1, up 4<br />Write the Equation in Standard Form<br />
8. 8. y<br />5<br />5<br />x<br />O<br /> 5<br />5<br />Vertex: ______________<br /> <br />Axis of Symmetry: _________<br /> <br />Direction: __________<br /> <br />Root(s): _______ ________<br />down<br />-10, 67<br />1/2<br />3<br />9/2<br />9/2<br />3<br />1/2<br />
9. 9. Describe the Transformation<br />Reflect over x-axis,<br />Vertical Compression ½ ,<br />right 3, up5<br />Write the Equation in Standard Form<br />
