Domain is the set of all permissible x values. The Range is the set of all y values that result when you substitute the permissible x values from the domain. One way to find the domain and range is to draw the graph, especially if you have a graphing calculator.
Another way to find the domain is to solve the equation for y in terms of x, and determine all the forbidden values of x. This means to be careful to NOT allow denominators to be zero, and make all RADICANDS greater than or equal to zero.
To find the range, you can solve for x in terms of y to see what values of y are allowed or not allowed in the equation that results. This means, as when finding the domain, to make sure the denominators cannot equal zero, and make sure radicands are greater than or equal to zero.
