How do you find horizontal and vertical asymptotes? I know that for Horizontal I must find the left and right limits of infinity but I'm not sure about vertical asymptotes.
for rational functions like \(\large f(x)=\frac{g(x)}{h(x)} \), it's what makes g(x) = 0...
alright well if you have a rational function. you get a vertical asymptote if the denominator is zero
or like what dpalnc said in a better way
so usually in elementary calculus you just have some polynomal, then you just gotta factor it and find the roots of the polynomial
or a trig function or something
Ohh okay thanks for the help, I appreciate it. Also for the polynomial, when I find the roots , how are those included in my graph?
if you have y = f(x) then the roots tell you were y=0 it is where the curve crosses the x-axis
in addition to the rational function i mentioned, g(x) and h(x) must be relatively prime.....
Oh I get it now, thanks a lot!
