The intercepts are where the function graph crosses an axis. For example, your x-intercept is (5,0) because the function crosses the x-axis at this point. The y-intercepts are (0, +/- 1.5). The domain is whatever x-coordinates are crossed, in this case, -3 < x </= 5. The range includes any y-coordinates that are crossed. -2 < y < 2.
