Answer:
x is the independent variable
Step-by-step explanation:
In the context of a function, the independent variables are the inputs to the function and the dependent variables are the outputs of the function.
A variable in an equation that may have its value freely chosen without considering values of any other variable.
For equations such as y = 2x + 3, the independent variable is x. The variable y is not independent since it depends on the number chosen for x.
