This math topic focuses on determining the domain of functions that involve the square root of a linear expression in the numerator and the square root of a quadratic expression in the denominator. Specifically, learners are tasked with mapping the real roots of these expressions on a number line. Each problem presents a different function, and students must choose the correct number line representation of the domain for each function.
