if you have two output values for a given input it doesn't meet the definition of a function.  continuity is about the limit and function value being equal

anonymous · Answer

a function F(x) is continuous at x=a if  the limit as x ->a exists and is equal to the value of the function there F(a)

what class is this for?  I guess the best definition to give you depends on which course you are taking
