This math topic focuses on determining the domain of functions involving fractional expressions with square roots in both the numerator and the denominator. It involves solving expressions where linear terms are placed under square roots, requiring students to analyze the conditions under which the expressions within the roots do not result in undefined operations (like taking the square root of a negative number). The problems are presented in a multiple-choice format, where learners must select the correct domain from given options.
