Question

How do you find the asymptotes for `f(x)=(1-2x)/sqrt(1+x^2)`?

Answer 1

You find the asymptotes by subbing a number into x, in order to find the value which is undefined.

Explanation:

`f(x)` = `(1-2x)/(sqrt(1+x^2)`

`f(-1)` = `(1-2(-1))/(sqrt(1+(-1)^2)`

= Underfinded

`:.` `-1` is the asymptotpe
