Question

baldymcgee6 · Answer

If the $$\lim_{x \rightarrow \infty} f(x) =c$$ what is the equation of the vertical asymptote?

precal · Answer

depends on f(x)

baldymcgee6 · Answer

right, the answer is y = c, but that would just be a horizontal line, I think the question is supposed to be 'what is the equation of the horizontal asymptote'.

precal · Answer

(y=number) is a valid equation of a horizontal asymptote, not sure if y=c is the correct answer

baldymcgee6 · Answer

It's a valid equation for a horizontal asymptote, but not a vertical asymptote

baldymcgee6 · Answer

The answer provided from the professor is y=c, but I think the question is wrong.

precal · Answer

Did you copy the correct question down?  Was it written down or spoken to you?  Everyone makes mistakes, even professors from time to time (rare though)

precal · Answer

the vertical asymptote is whatever makes the function undefined.  Unless you were given a specific f(x)

So do you think this question/answer is wrong?

precal · Answer

I would hate to judge this one statement.  It looks incomplete to me........

precal · Answer

go talk to your professor, just be respectful.....

baldymcgee6 · Answer

okay, I will, thanks for the help

precal · Answer

something wrong with this website, my postings are in the wrong order

baldymcgee6 · Answer

yeah, openstudy seems to be glitching for me too

precal · Answer

oh well, I wonder if they know.........

baldymcgee6 · Answer

I think it's because of the new updates they put in yesterday.

precal · Answer

perhaps, well nice talking to you
