Goten77 Group TitleBest ResponseYou've already chosen the best response.1
but we need the vertical asymptote so we needa find the x value so we put the equation in the form of x = #
 one year ago

Goten77 Group TitleBest ResponseYou've already chosen the best response.1
so now we use the original equation and use that y value to solve for the x

this is basically the quotient rule + implicint differentation + production rule + chain rule THEN use that negative .... you dont have to simplify unless ur told to.. which i dont think u can
