- 1Algebraic ExpressionA combination of variables, numbers, and operations (like +, −, ×, ÷) that does not include an equals sign. Example: 3x+23x + 2.
- 2VariableA symbol (usually a letter) that represents an unknown or changeable value. Example: xx, yy.
- 3TermA single part of an expression or equation, made up of numbers and/or variables.
- 4PowerAn expression that represents repeated multiplication of the same factor.
- 5CoefficientThe numerical factor of a term that contains a variable.
- 6EquationA mathematical statement that two expressions are equal, using an equals sign. Example: 2x+3=72x + 3 = 7.
- 7SolutionA value (or set of values) that makes an equation or inequality true.
- 8IdentityAn equation that is true for all values of the variable(s). Example: x+0=xx + 0 = x.
- 9RelationA set of ordered pairs, showing how elements from one set are connected to elements of another. Can be represented as a table, graph, or equation.
- 10DomainThe set of all possible input values (usually xx) for a function or relation.
- 11RangeThe set of all possible output values (usually yy) for a function or relation.
- 12Independent VariableThe variable that you control or choose; it determines the value of the dependent variable. Usually xx.
- 13Dependent VariableThe variable that depends on the independent variable. Usually yy.
- 14FunctionA relation in which each input has exactly one output. Example: f(x)=x2f(x) = x^2.
- 15InterceptThe point where a graph crosses the axes.
- 16Line SymmetryA property where one half of a graph is a mirror image of the other across a line (often the y-axis or x-axis).
- 17End BehaviorDescribes what happens to the values of a function as xx approaches positive or negative infinity. Example: Does the graph rise or fall at the ends?
