Explain how to determine the domain and range of a function. Give specific techniques for each type of function and clarify how the domain and range are expressed. It is not sufficient to state that the domain is the x-values and the range is the y-values. There are example problems listed with each type of function. Do not type the solutions to these problems into the discussion board posting. Clearly organize the posting by referring to A, B, and C.

A) How do you determine the domain and range of a function expressed with a graph? In section 2.2, #54b and #58a are functions expressed with a graph.

B) How do you determine the domain and range of a function expressed with a set of ordered pairs? In section 2.1, #26 is a function expressed with a set of ordered pairs.

C) How do you determine the domain and range of a function expressed with an equation? In section 2.2, #18 and #24 are functions expressed with an equation.
