Shows the graph of a function y = (x). Copy the graph and draw in the line

Shows the graph of a function y = ƒ(x). Copy the graph and draw in the line y = x. Then use symmetry with respect to the line y = x to add the graph of ƒ^-1 to your sketch. (It is not necessary to find a formula for ƒ ^-1.) Identify the domain and range of ƒ^-1.
