## shahzadjalbani 3 years ago Describe Irrational functions and explain how to calculate asymptotes.

1. lgbasallote

2. lgbasallote

you can calculate for vertical asymptote by equating y to infinity and solving for x...usually this happens in rational expressions only

3. lgbasallote

rational expressions/functions are expressions/functions with a variable in the denominator

4. lgbasallote

so vertical asymptotes will happen when there is an x in the denominator...im thinking horizontal asymptotes will happen when there is a y in the denominator

5. lgbasallote

would you like an example?

Yes ................

7. lgbasallote

i'll give a simple one y = 1/x you'll notice that if x = 0 then y would be undefined..you have discussed that right?

8. lgbasallote

i mean that 1/0 is undefined..you know that right?

Thanks @lgbasallote now I am going for the Lunch BRB after lunch.

10. lgbasallote

well i have to go as well ^_^ but i assume you know the rest

11. lgbasallote

from my example x = 0 (a.k.a. the y-axis) is the vertical asymptote

12. lgbasallote

horizontal asymptotes will appear in 1/y = x just do the same process
