Study Notes
Linear Expressions and Equations
- Linear expressions involve variables and constants combined with addition, subtraction, and multiplication.
- Linear equations describe relationships between variables, often represented by a straight line on a graph.
Creating Linear Equations
- Equations can be created from various contexts.
- Equations can be formed using two points or a graph.
- Linear inequalities can be created and solved.
Proportional vs. Non-Proportional Relationships
- Proportional relationships maintain a constant ratio between variables.
- Non-proportional relationships do not exhibit this constant ratio.
- Different representations of proportional relationships exist.
Rate of Change and Initial Value
- Rate of change describes how a variable changes over time.
- Initial value represents the starting point of a relationship.
Arithmetic Sequences
- Arithmetic sequences involve a constant difference between consecutive terms.
- Explicit and recursive formulas define these sequences.
Linear Graphs
- Linear graphs are straight-line representations of relationships between variables.
- Graphs can be interpreted to understand the relationship.
Domain and Range of Linear Graphs
- Domain refers to the set of possible input values (x-values).
- Range refers to the set of possible output values (y-values).
- Interval and set notation describe domains and ranges.
Function Notation
- Function notation represents a relationship between variables.
- Function notation can be applied to tables and graphs.
Linear and Non-linear Functions
- Linear functions result in a straight-line graph.
- Non-linear functions produce non-straight graphs.
- Parent functions represent basic forms of functions.
- Key features describe critical characteristics of functions.
