To find the slant asymptote of the rational function \( r(x) = \frac{-x^3 - 13x^2 - 35x + 3}{x + 9} \), you need to perform polynomial long division. When you divide \( -x^3 - 13x^2 - 35x + 3 \) by \( x + 9 \), you'll find that the quotient gives you the linear equation for the asymptote, while the remainder can be ignored for large values of \( x \). Upon dividing, you'll find that the slant asymptote is: \( y = -x^2 - 4x + 3 \). Thus, the slant asymptote is \( y = -x^2 - 4x + 3 \).
