This topic focuses on finding the domain of functions that are represented as a ratio of an integer to a quadratic expression. The problems involve scenarios where the quadratic has complex roots. The main skill practiced here is identifying and expressing the set of all possible x-values (the domain) for which each function is defined. This involves understanding where the functions potentially have undefined points (due to zero denominators), and mathematically determining how to express those domains correctly using set notation.
