Predict whether the product the second factor. Then comp po 5 7 9 = X Predict: x 9

you need to add a picture

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

i believe that the answer is y+6=1/3(x+2)
