So you would say this is equal to negative infinity. And of course, if you said the limit as x approaches zero from the right of one over x, well, here, you're unbounded in the positive direction, so that's going to be equal to positive infinity. Let's do an example problem from Khan Academy based on this idea and this notation. So here it says, consider graphs A, B, and C. The dashed lines represent asymptotes. Which of the graphs agree with this statement that the limit as x approaches one of h of x is equal to infinity? Pause this video and see if you can figure it out. All right, let's go through each of these.
