Hello! I don't understand how to do these problems. I've tried to read the explanations but I just don't get it.

1. The graph of a rational function} is shown below. Assume that all asymptotes and intercepts are shown and that the graph has no "holes". Use the graph to complete the following. (3) Write the equations for all vertical and horizontal asymptotes. Enter the equations using the "and" button as necessary. Select r'None" as necessary. I -' Vertical asvmptote(s): I: IS '5 I .
