Independent & Dependent Variables
Dependent Variables
A dependent variable is a variable whose value relies on the values of one or more independent variables.
For example:
For example:
1. In p = 4q, p is the dependent variable, because its value depends on the value of q.
2. In z = 3x2 - 2y3, z is the dependent variable.
2. In z = 3x2 - 2y3, z is the dependent variable.
Example What is the dependent variable in the function y = 3 - x?
The value of y depends on the value of x therefore, y is the dependent variable.
