Practice Problems
1 : Determine if the following function has any vertical asymptotes.
What is the sum of the values which have vertical
asymptotes?
Remember that vertical asymptotes occur when you have some kind of “non-zero over zero” type
situation happening at a point. Try finding all the domain restrictions as a starting point if you are having trouble.
