Hi guys! This video discusses how to find the domain and range of functions. Domain and Range are the set of permissible values for x and y, respectively. When finding domain and range of functions, we take note of the cases where there is a radical expressions whose index is even and also for the rationale algebraic expressionss. That is the radicand mus be greater than or equal to zero and the denominator of rational expressions. We can also use graphs to visualize the function and therefor, you can now analyze further circuit. Happy leanrning and enjoy watching! #tagalog #math #greatestshowman
