<PRE><B>Question 379959</B>
how you find the function rule in a problem and how can you tell if it is independent or a dependent variable
-------
If the rule of the relation generates one y value for each x value,
the relation is called a function.
----
The variable value you choose to insert into the rule is the independent
variable.  The variable value generated by the rule is the dependent
variable.
