Divide two functions then determine the domain

The video tutorial explains the process of dividing functions, specifically F(x) by G(x), and highlights the importance of considering domain restrictions when performing such operations. It emphasizes that while adding, subtracting, and multiplying functions, the domain is simply the intersection of the individual domains. However, division introduces additional constraints, as the denominator cannot be zero. The tutorial provides a detailed explanation of how to determine the domain of the resulting function, ensuring that the denominator does not equal zero, and clarifies that the domain of X^2 + 4 is all real numbers, while the domain of the division operation is (4, Infinity).
