Vertical asymptotes occur where the denominator of a rational function is zero (and the numerator is not zero at those points). For the given function, set the denominator equal to zero and solve for $x$: $3x^2 - 5x - 8 = 0$. Factoring or using the quadratic formula gives the roots $x = \frac{8}{3}$ and $x = -1$, which are the vertical asymptotes.
