Based on a particular mathematical structure of a certain function f (x) under our attention, we present a novel quantum algorithm. The algorithm allows one to determine the property of a certain function. In our study, it is f (x) = f (-x). Therefore, there would be a question here, "How fast can we succeed in this?" All we need to do is only the evaluation N of a single quantum state [GRAPHICS] (N >= 2). Only using that with a little amount of information, we can derive the global property f (x) = f (-x). Our quantum algorithm overcomes a classical counterpart by a factor of the order of 2(N).
