Asymptotes
Is there a way to deduce asymptotes(horizontal,vertical,oblique) of a function without graphing the function?

Re: Asymptotes
hi Berniard,
Welcome to the forum!
Yes, there is. Have you got a function for me to demonstrate on?

goes through all the steps for sketching a graph from its function.

Re: Asymptotes
So,by checking where the graph tends to infinity I can know the asymptote?

Re: Asymptotes
hi Berniard,
That's about right. When a denominator is zero, the value of y 'goes to infinity'. Those are vertical asymptotes.
The others are found when you consider what happens when x tends to + or - infinity.
