Determine if the function below has a horizontal or a slant asymptote, and explain why. \[ f(x)=\frac{-13 x-10 x^{2}+5}{-2 x-3} \] Answer Attempt 1 out of 2 The function has a \( \quad \vee \) asymptote because the degree of the numerator is \( \quad \vee \) the degree of the denominator. As \( x \) approaches infinity (positive or negative), the value of \( y \) approaches \( \begin{array}{l}\text {. }\end{array} \)

To determine the nature of the asymptote, we start with the degrees of the numerator and the denominator. The numerator \( -13x - 10x^2 + 5 \) has a degree of 2 (due to the \( -10x^2 \) term), while the denominator \( -2x - 3 \) has a degree of 1. Since the degree of the numerator is greater than the degree of the denominator by one, there is a slant asymptote. We can find this by performing polynomial long division. As \( x \) approaches infinity (positive or negative), the value of \( y \) approaches the slant asymptote given by the quotient from the division, which will be a linear function of the form \( Ax + B \), where \( A \) and \( B \) are the coefficients obtained from the division. Keep your eyes on that long division magic!
