Each of the problems below is a link. If you click on the problem, it will take you to a YouTube video of a full, step-by-step solution for the problem. You may try these problems as practice and use the videos to check your answer, or you can just watch the videos to see more worked-out example problems.

Use the graph of f of x = the absolute value of x, + 3 to find f of negative 1 and f of 2. For which value or values of x is f of x equal to 5? Then, find the domain and range of f.
Use the graph of g of x = the absolute value of x + 3, to find g of negative 1 and g of 2. For which value or values of x is g of x equal to 5? Then, find the domain and range of g.
Use the graph of f of x = the square root of x, minus 2 to find f of 1 and f of 4. For which value or values of x is f of x equal to 0? Then, find the domain and range of f.
Use the graph of g of x = the square root of x minus 2, to find g of 1 and g of 6. For which value or values of x is g of x equal to 0? Then, find the domain and range of g.
