Which of the following statements is true? a) the dependent variable is the input of the function. b) the dependent variable determines the domain of the function. c) in f(x)=2x+1, x is the dependent variable. d in f(x)=2x+1, f(x) is the dependent variable.

Dependent variable:

Dependent variables are variables which depend on another variable

For example:

Here , we can see that value of y is dependent on x

so, y is dependent variable

and y is also output variable

while

x is independent variable

x is also input variable
