Nikia made the following statement, "I grouped these together because they all show vertical symmetry. If I draw a vertical line through the middle of the graph, the image is the same on both sides."
Using the line tool, show why Nikia's reasoning is correct .
If possible, identify the letter of other graphs that show vertical symmetry.
Duane grouped the following graphs together because each graph only goes through two quadrants.
Explain why Duane's reasoning is not correct.
If possible, identify other graphs that only go through two quadrants.
Josephine grouped these four graphs together, but did not provide any rationale.
What do you notice about the graphs? What rationale could Judy have provided?
