What are the Steps for Finding Vertical Asymptotes in Polynomial Functions?

Click For Summary
SUMMARY

The discussion focuses on the process of finding vertical asymptotes in polynomial functions, specifically using the polynomial 2x^3 - 4x^2 - 2x + 4. Participants emphasize the importance of factoring the denominator correctly, which in this case can be simplified to 2x^2(2x - 4) - 1(2x - 4). The key takeaway is that vertical asymptotes occur where the function is undefined, typically at the roots of the denominator after factoring.

Alright, I know how to find the horizontal asymptotes

but the vertical asymptotes?

I tried dividing the polynomials but maybe I am not doing it correctly because I cannot get a normal answer...

and I am unsure how to factor the denominator.
 
Physics news on Phys.org
2x^3-4x^2-2x+4=2x^2(2x-4)-1(2x-4)

does that help you?
 
yes that makes more sense thanks

didn't consider that
 
and then just check to see what makes the function undefined
