Answer 2

Same as last time. We want the x-values, so we have {1,3,5,7}. Remember that the x-values are the first number in the ordered pair.

Answer 3

Okay, so now range is the y values. The y values of the coordinates given are (3, 5, 7, 9) So the answer is B! =)

A good way to remember which is which for domain and range is that d comes before r and x comes before y. So, that way you know domain=x and range=y!

Hope that helps and sticks witcha...

Answer 4
