To write the domain in interval notation, we need to use three intervals and use the vertical asymptotes for endpoints of the intervals. Domain: {eq}(-\infty, -2)\cup (-2, 1)\cup (1,\infty) {/eq}
!How To: Given a rational function, identify any vertical asymptotes of its graph. Factor the numerator and denominator. Note any restrictions in the domain of the function. Reduce the
