The function must work for all values we give it so it is up to us to make sure we get the domain correct. In its simplest form the domain is the set of all the values that go into a function. We can write the domain of f x in set builder notation as x x 0.
The range of a function f x is the set of all.
I highly recommend that you use a graphing calculator to have an accurate picture of the. In mathematics the domain of a function f x is the set of all values of x that can be plugged into f x to produce a defined function. The function must work for all values we give it so it is up to us to make sure we get the domain correct. The graph may continue to the left and right beyond what is viewed but based on the portion of the graph that is visible we can determine the domain as 1973 t 2008 and the range as approximately 180 b 2010.
