This math topic focuses on analyzing rational function inequalities, specifically determining the intervals where given rational functions maintain a constant sign. The problems involve polynomial expressions with multiplicity in the numerator and denominator formulated in factored form. The primary goal is to identify sets of open intervals where these rational functions do not change their sign, considering various factors such as roots and points of undefined behavior. Each problem requires an understanding of function behaviors across different intervals on a number line.
