5. The range represent the y-values of the ordered pairs, and the domain the x-values. So among the ordered pairs, (0, -2) has a range value of -2
6. In a function, a number in the domain must only appear once in the set of ordered pairs. Since in letter B we have (1, 3) and (1, 2), therefore it is not a function.
7. Using the vertical line test, we can see that Graph 1 did not pass the test since it intersect the graph more than once (twice to be precise)
