The valid values for a given independent variable x are collectively called the domain.

Find domain and range examples.

So i will let the stuff inside the radical equal or greater than zero and then solve for the required inequality. Find the domain and range of the function. Find the domain and range of the radical function the acceptable values under the square root are zero and positive numbers. Without using a graph.

Square root of cos x. For example in the function y f x 2 x y x is independent and y is dependent in other words y is a function of x. The valid values for a given dependent variable y are collectively called the range. Finding domain and range from a graph of oil production.
