This math topic focuses on the behavior of rational functions, particularly how their signs change at specific points. The problems involve checking if the sign of a rational function that consists of three factors in the numerator and a binomial in the denominator changes at a designated value of the variable \(x\). This involves understanding the factors of the numerator and denominator and determining their values at specific points to observe if there is a sign change due to crossing over zeros. These exercises enhance students’ abilities to analyze and interpret the properties of rational functions in algebra.
