Writing the domain of a rational function with the radical in the numerator

The video tutorial explains the concept of implied domain in functions, focusing on identifying domain restrictions. It covers how to handle non-real numbers, such as those resulting from division by zero or taking the square root of negative numbers. The tutorial also discusses domain constraints and provides solutions, emphasizing the importance of setting denominators to zero and radicals to non-negative values. Finally, it illustrates how to represent the domain graphically using a number line.
