WebFinding Limits Graphically. By the end of this lecture, you should be able to use the graph of a function to find limits for a number of different functions, including limits at infinity, and to determine when the limits do not exist (and when they do not exist, to explain why). You should also be able to use limit notation correctly. WebRemember that limits represent the tendency of a function, so limits do not exist if we cannot determine the tendency of the function to a single point. Graphically, limits do not exist when: there is a jump discontinuity (Left-Hand Limit #ne# Right-Hand Limit) The limit does not exist at #x=1# in the graph below. there is a vertical asymptote
