Question

1. If you only had the graph of a relation on a piece of grid paper, how could you graph the inverse without listing the ordered pairs?

2. What do you notice about the ordered pairs which lie on the fold?

3.What do you notice about the two sets of points you graphed?

4.List the inverse of the relation.

5. Draw a line on the fold. List five ordered pairs on the fold.

6. Unfold the paper. Describe where the fold is on the graph.

Answer 1

are you given a graph? ordered pairs? something?
the answer to the first question you have already
1) reflect about the line y = x
2) if you fold the paper along the line y = x you will see that the ordered pairs on the fold have the same first and second coordinate
3) not sure what this is asking.
4) the inverse relation will have the ordered pairs switched. so if (a,b) is on the graph of the relation, (b,a) will be on the graph of the inverse relation
5) we cannot do that without the list right?
6) ditto
