                       ArrayList<Object> parameterValues)

Evaluate the function with the given ID using the given parameters, e.g. f(10,29)

Parameters:

functionID - ID of the function to evaluate

parameterValues - Parameter set to use in evaluation

Returns:

Value of the function evaluated using the given parameters
