Study Notes
Variables
- Independent Variable (IV): Represents the input of a function (denoted as x).
- Dependent Variable (DV): Represents the output of a function (denoted as y).
Function Characteristics
- Domain: The complete set of input values (x values) for a function.
- Range: The complete set of output values (y values) for a function.
Measurements
- Rate: A measure, quantity, or frequency compared to another quantity.
- Scale: A series of ordered marks or intervals used for measurement.
Data
- Data: Information gathered through observation or experimentation.
Graph Components
- X Axis: The horizontal line on a graph.
- Y Axis: The vertical line on a graph.
Graph Types
- Discrete Graphs: Composed of distinct points on a graph.
- Continuous Graphs: Display a solid line with no breaks in data.
Quadrants
- Quadrant 1: Where both x and y values are positive (+,+).
- Quadrant 2: Where x is negative and y is positive (-,+).
- Quadrant 3: Where both x and y values are negative (-,-).
- Quadrant 4: Where x is positive and y is negative (+,-).
Representation Forms
- Graphical Representation: The visual display of data shown through plots and charts.
- Symbolic Representation: Represents data using equations.
- Numerical Representation: Represents data using tables.
- Concrete Representation: Represents data through pictures and drawings.
- Verbal Representation: Represents data through narrative or story problems.
Sequences
- Sequence: An ordered list of numbers, such as 2, 4, 6, 8, 10.
Directions
- Horizontal: Refers to going across.
- Vertical: Refers to going up and down.
Axis
- Axis: The reference lines that define the coordinate system on a graph.
