The "output" value of a function.

(It is called dependent because its value depends on what you put into the function.)

Example: y = x^{2}

• x is an Independent Variable

• y is the Dependent Variable

y is 4 if we put in x=2

y is 9 if we put in x=3, and so on

(See how y gets pushed around by x? That isn't nice at all.)

Example: h = 2w + d

• w is an Independent Variable

• d is an Independent Variable

• h is the Dependent Variable
