How do you find the equations of the vertical and horizontal asymptotes for a graph when you only have the graph and no function?

Question

How do you find the asymptotes for a graph when you don't have the function? Also, is the function f(x) = a/x just when the asymptotes both intersect 0?

Answer 1

you can find Vertical Asymptoties by putting the demeanor of the Rational function =0. For Example: f(x)=a/x put. X=0 that means all the points that X=0 is Y-Axis is Vertical Asymptote.

To find Horizontal Asymptote put Numerator =0

it means Y=0 means X-Axis is H.A
