Study Notes
Understanding Relations
- A relation is defined as a set of input-output pairs.
- Input-output rules use input values to determine corresponding output values.
Input-Output Rules
- An example rule takes an input, applies a mathematical operation, and results in an output.
- For example, input of -5 yields an output of -15 by applying a specific rule.
Collaborative Activities
- Partner activities involve identifying rules and completing input-output tables based on various mathematical operations.
- Rules can include adding or subtracting constants, as well as multiplying or dividing values.
Mapping Diagrams
- Relations can also be represented using mapping diagrams, which visually display how inputs are connected to outputs through arrows.
- Each input corresponds to exactly one output in a mapping diagram.
Graphical Representation
- Each relation can be illustrated using graphs, where points represent input-output pairs.
- The graph directly reflects the relationships shown in the mapping diagram.
Terminology in Relations
- Inputs are considered independent variables, while outputs are dependent variables.
- A graph represents the set of ordered pairs, linking x-values (inputs) to y-values (outputs).
Comparing Representations
- Observations can be made by comparing mapping diagrams and graphs for insights into input-output relationships.
- Each representation (table, mapping, graph, ordered pairs) provides a different visual or mathematical insight into the same relation.
Additional Notes
- The ability to recognize relations in multiple forms is a vital skill in understanding foundational mathematical concepts.
- Complete practice activities in pairs to reinforce understanding of input-output rules and their representations.
