Create a function that has 2 vertical asymptotes
a) provide an analysis for the behavior of the function around the vertical asymptotes.
y = 1/((x+1)(x-3))
make a rough sketch of the graph, then do the analysis.
copy and paste, delete the 2 spaces at the front before activating the link

The first graph shows only the bottom loops,
the second graph shows the full picture, I am sure you detect
the asymptotes
you might also want to consider
y = 1/((x+1)(x-3)^2)
