Examine
Which
-values have points on the graph? That is, describe the domain of . The domain includes
and all the numbers between. What are the possible outputs for
? That is, what is the range? The domain includes
, and all the numbers between. Ricky thinks the range of
is: . Is he correct? Why or why not? Is there a point on the graph for
? or for ? He is not correct since he is missing all the values between his numbers.
The curve is continuous, so the description needs to include all numbers, not just integers.Draw a graph for another function with the same domain and range as
. There are many possibilities. Here is one example.
