Chapter 4: Section 1 Notes
By the end of the section, you should be able to:
- Graph a quadratic function in Vertex Form.
- Describe the transformations of an Quadratic Equation in Vertex Form ( y = a ( x - h )^2 + k)
- Find the vertex of a Quadratic function in Vertex Form.
Definitions:
- Parent Function: the simplest form of a function (ex. y = x^2)
- Quadratic Function: a function when x is raised to the 2nd power.
- Also known as a second degree function.
- Parabola: the graph of a quadratic function.
- Vertex Form: y = a (x – h)^2 + k
- a cannot be 0
- Axis of Symmetry: a line that divides the parabola into two mirror images. x = h
- Vertex: The center ‘point’ of the parabola ( h , k )
- Minimum Value: the smallest y-value of a function.
- Maximum value: the largest y-value of a function.
