Final answer:
In the given function zxyxy, the independent variables are x and y, and the dependent variable is z.
Step-by-step explanation:
The independent variable is the variable that is controlled or manipulated in a function, while the dependent variable is the variable that changes with the value of the independent variable. In the given function zxyxy, since the function is defined by the variables x and y, the independent variables are x and y, and the dependent variable is z.
