The equations of the asymptotes of the curve with the equation-
2. The zeros of the denominator will yield the equations of the vertical asymptotes.
3. Re-arrange the given equation by long division:
That means you'll get a horizontal asymptote since the term of the asymptote is a constant (the slope is zero)
And no johnsy, you can't substitute because is not a number. But you can think about what would happen as your function gets infinitely large in either direction...
