• The number of tenans in floor 20 is equal to c

• The floor c is equal to 20

• The number of tenans in floor 20 is equal to the number of tenans in floor c

What impact does restricting the domain of a linear function have on the graph of the function?

How does slope determine the end behavior of a linear function with an unrestricted domain?

For the given function and domain, draw the graph and identify the range using the same notation as the given domain.
