| Question | Answer |
| Algebraic Expression | A combination of variables, numbers, and operations (like +, −, ×, ÷) that does not include an equals sign. Example: 3x+23x + 2. |
| Variable | A symbol (usually a letter) that represents an unknown or changeable value. Example: xx, yy. |
| Term | A single part of an expression or equation, made up of numbers and/or variables. |
| Power | An expression that represents repeated multiplication of the same factor. |
| Coefficient | The numerical factor of a term that contains a variable. |
| Equation | A mathematical statement that two expressions are equal, using an equals sign. Example: 2x+3=72x + 3 = 7. |
| Solution | A value (or set of values) that makes an equation or inequality true. |
| Identity | An equation that is true for all values of the variable(s). Example: x+0=xx + 0 = x. |
| Relation | A 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. |
| Domain | The set of all possible input values (usually xx) for a function or relation. |
| Range | The set of all possible output values (usually yy) for a function or relation. |
| Independent Variable | The variable that you control or choose; it determines the value of the dependent variable. Usually xx. |
| Dependent Variable | The variable that depends on the independent variable. Usually yy. |
| Function | A relation in which each input has exactly one output. Example: f(x)=x2f(x) = x^2. |
| Intercept | The point where a graph crosses the axes. |
| Line Symmetry | A property where one half of a graph is a mirror image of the other across a line (often the y-axis or x-axis). |
| End Behavior | Describes 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? |
