  • Relation
    A connection between X and Y values, represented as ordered pairs, where each input can correspond to one or more outputs.
  • Function
    A special type of relation where each input is paired with at most one output, ensuring no input has multiple outputs.
  • Input
    An X value in a relation or function, representing the independent variable or starting value in an ordered pair.
  • Output
    A Y value in a relation or function, representing the dependent variable or resulting value in an ordered pair.
  • Ordered Pair
    A notation (x, y) showing the relationship between an input and its corresponding output on a graph.
  • Vertical Line Test
    A graphical method to determine if a graph represents a function by checking if any vertical line crosses more than one point.
  • Domain
    The complete set of allowed X values for a relation or function, often found by projecting the graph onto the X-axis.
  • Range
    The complete set of allowed Y values for a relation or function, often found by projecting the graph onto the Y-axis.
  • Interval Notation
    A concise way to express domain or range using brackets and parentheses to indicate inclusion or exclusion of endpoints.
  • Set Builder Notation
    A notation using inequality symbols to describe domain or range, specifying the conditions that elements must satisfy.
  • Bracket
    A symbol used in interval notation to indicate that an endpoint is included in the domain or range.
  • Parenthesis
    A symbol used in interval notation to indicate that an endpoint is excluded from the domain or range.
  • Union Symbol
    A symbol used to connect multiple intervals in domain or range, indicating the combination of separate sets.
  • Squish Strategy
    A visual technique where a graph is compressed onto an axis to reveal the domain or range.
  • Open Circle
    A graphical marker indicating that a specific value is not included in the domain or range.
