## variableThe algebraic quantity whose numerical value may change. The most-used symbols in elementary algebra are x and y. If one variable is
a function of the other, as in the equation
y = ax^{2} + bx + c, where a,
b, and c are constants,
then y is termed the dependent variable, since
its value depends on the value of the independent variable
x. See also parameter. ## Related category• ALGEBRA | |||||
