True or False?
The function g has a domain of {2,4,6,8} and a range of {3,5,7}.Could g be represented by the set of ordered pairs {(2,3),(4,5),(6,7),(8,3)} Justify your answer.
True, ranges can repeat and still represent a function.

Draw three DIFFERENT graphs that are NOT functions
Must fail the VLT

Is the following set of ordered pairs a function? Why or why not?
{(0, 1) (0, 2) (0, 0) (0, -2) (0, -8)}
No - not a function. Because we have multiple x-values that have the same y-value. Does not pass the vertical line test.
