Domain function help?

Pleeease help find domain & asymptotes of this function. HELPPP pleease? D:?

  • Find the domain of the function and identify any horizontal and vertical asymptotes. f(x)=2x^2/(x+1) also-- if you could please help me out with this one too b/c these were the two i was stuck on: Find the zeros (if any) of the rational function. g(x)=x^3-8/(x^2+1) thank you!!! i really appreciate this <33

  • Answer:

    Domain = ( - ∞ ; 1) ⋃ (1 ; + ∞ ) Vertical asymptote: x = - 1 Find the zeros (if any) of the rational function. x^3 - 8/(x^2 + 1) = 0 x1 = 1.39509733419441, x2 = 0.418461452074741 + 1.57389174086045*i, x3 = - 1.11601011917194 + 0.957393151717780*i, x4 = - 1.11601011917194 - 0.957393151717780*i, x5 = 0.418461452074741 - 1.57389174086045*i
