S'ok. But the question is still odd, because the values of the function don't have anything to do with whether the two limits are equal. If a function is continuous at x=3, what can you say about it's left and right hand limits? Do you mean to say k(x) is only defined on the interval [3,4]? Or is it defined and continuous everywhere?sorry i typed the question wrong k(3)=-1

k(x) is continuous for all real numbersS'ok. But the question is still odd, because the values of the function don't have anything to do with whether the two limits are equal.
