This math topic focuses on finding the domain of functions where the function is given as a fraction with a linear numerator and a linear-expression square root in the denominator. Students are required to determine the set of all possible x-values (domain) that will make the function defined, by ensuring the expression under the square root is non-negative. The questions are structured as multiple choice, where students select the correct domain from provided options.
