Dependent Variable

Dependent Variable

The output value of a function.

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

Example: y = x2
• x is an Independent Variable
• y is the Dependent Variable
y becomes 4 when we put in x = 2
y becomes 9 when we put in x = 3, and so on

Example: h = 2w + d
• w is an Independent Variable
• d is an Independent Variable
• h is the Dependent Variable
