I have a math 12 final in about two hours and the only thing I can't seem to figure out is how to find the asymptote when you can't use a calculator to graph it? For example I've seen questions such as
2. Which of the following is an asymptote of the graph of the function y = cotx
5. Which of the following lines is an asymptote for the graph of y = sec x ?
Does anyone know a rule to finding the asymptotes? What happens if there's a number in front of the x? Would that be too hard to figure out in your head?
