Yes, it is bijective. For every value in the domain, there is EXACTLY one value in the range AND for every value in the range, there is EXACTLY one value in the domain. Which is to say that BOTH the function AND its inverse are functions. You can also say that the function passes both the horizontal and vertical line tests over the given domain.
