# Unit 3: Quadratic Functions
|
|
|
|
## Definitions
|
|
- `Linear relation`: A relation with a constant rate of change
|
|
- `Non-linear relation`: A relation with a variable rate of change
|
|
- `Degree` of a polynomial: Highest exponent that appears in any term of a polynomial
|
|
- `a-value`: Step property
|
|
- `Axis of symmetry`: Vertical symmetrical line through a parabola, also x-value for vertex
|
|
- `Zeroes`: x-intercepts of parabola
|
|
- `Vertex`: Maximum or minimum value on a parabola
|
|
- `Optimal value`: y-value for vertex
|
|
- `Domain`: List of all valid x-values for relation, expressed as $`D = {num, num2, num3}`$ or as a relation such as $`D = {x E R, x != 0, x < 50`$
|
|
- `Range`: List of all valid y-values for relation, expressed as $`R = {num, num2, num3}`$ or as a relation such as $`D = {y E R, y != 0, y < 50`$
|
|
- `Relation`: Set of ordered pairs of numbers
|
|
- `Function`: A relation in which no y-coordinates share an x-coordinate (e.g., circles are not functions)
