Question

what are the vertical and horizontal asymptotes for the function (f(x)=\frac{x^{2}+x - 6}{x^{3}-1})?
vertical asymptote: (x = 1)
horizontal asymptote: none
vertical asymptote: (x = 1)
horizontal asymptote: (y = 0)
vertical asymptote: (x=-2,x = 3)
horizontal asymptote: (y = 0)
vertical asymptote: (x=-2,x=-3)
horizontal asymptote: none

Explanation:

Step1: Find vertical asymptotes

Set the denominator equal to zero. Given $f(x)=\frac{x^{2}+x - 6}{x^{3}-1}$, we solve $x^{3}-1 = 0$. Using the formula $a^{3}-b^{3}=(a - b)(a^{2}+ab + b^{2})$, where $a=x$ and $b = 1$, we have $(x - 1)(x^{2}+x + 1)=0$. The real - root of $x^{3}-1=0$ is $x = 1$ (since the discriminant of $x^{2}+x + 1$ is $\Delta=1^{2}-4\times1\times1=- 3<0$). So the vertical asymptote is $x = 1$.

Step2: Find horizontal asymptotes

Compare the degrees of the numerator and denominator. The degree of the numerator $n = 2$ and the degree of the denominator $m=3$. When $nightarrow\pm\infty}\frac{x^{2}+x - 6}{x^{3}-1}=0$. So the horizontal asymptote is $y = 0$.

Answer:

vertical asymptote: $x = 1$; horizontal asymptote: $y = 0$
