There is NO x-intercepts. There is NO y-intercepts. The domain is holed number line with the hole at x = 0. In other words, the domain is the set of all real numbers except x= 0. The range is the set of two numbers {-1, 1}. The graph consists of two rays, parallel to x-axis. One ray is y= -1 at< < . The other ray is y= 1 at < < .
