Find the Asymptotes f(x)=(x^4+1)/(x^2+5x-14)

Math
Find where the expression is undefined.
Since as from the left and as from the right, then is a vertical asymptote.
Since as from the left and as from the right, then is a vertical asymptote.
List all of the vertical asymptotes:
Consider the rational function where is the degree of the numerator and is the degree of the denominator.
1. If , then the x-axis, , is the horizontal asymptote.
2. If , then the horizontal asymptote is the line .
3. If , then there is no horizontal asymptote (there is an oblique asymptote).
Find and .
Since , there is no horizontal asymptote.
No Horizontal Asymptotes
