This math topic focuses on solving rational function inequalities that involve determining the sign of a function over various intervals. It explores rational expressions where the numerator and denominator are represented as products of polynomial factors, some raised to a power indicating multiplicity. Students are required to analyze these functions and determine, using sign charts, where the expressions are positive, negative, or undefined based on zeroes of the numerator and points of discontinuity from the denominator. This task helps students understand the behavior of rational functions across their domain.
