Graphs of Rational Functions (Prior Material Review): Using Desmos (Mp3://www.desmoscom/calculator), graph the following rational function and then sketch its graph below: Add the graphs of dashed vertical lines at and at along with a dashed horizontal line at . 1) What are these dashed lines called? 2) Provide the coordinates for all -intercepts and the -intercept and label them on the graph. Write the intercepts as ordered pairs. 3) Compare your graph to the rational function then comment on any similarities and any differences. I t4) Produce a rough sketch of a graph of a rational function that has the following characteristics: Vertical Asymptotes at and with a Horizontal Asymptote at. The rational function also has intercepts of,, and
