Dependent Variable is a variable whose value depends on the values of one or more independent variables.
In p = 4q, p is the dependent variable, because its value depends on the value of q.
In z = 3x2 - 2y3, z is the dependent variable.
A. no dependent variable
Correct Answer: C
Step 1: In the function f(x) = 3 - x, the value of f(x) depends on the value of x. So, f(x) is the dependent variable.
