Coefficient | a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g., 4 in 4x y). |
Domain | the set of possible values of the independent variable or variables of a function. |
Equation | a statement that the values of two mathematical expressions are equal (indicated by the sign =). |
Expression | a collection of symbols that jointly express a quantity. |
