do you know what a vertex and axis of symmetry is?

4. Kagome_gurl8

yes

So we have a fancy bowl here. The vertex is the location we pour the cereal into, whether it's Captain Crunch, Cocoa Crispies... whatever it maybe, aim for the vertex when you pour. Do you understand how to read the graph? It looks like the cereal bowl has been shifted 2 units to the right, doesn't it? :D

6. Kagome_gurl8

Yes, it does.

7. zepdrix

So the vertex is located at (2,0). yay.

8. zepdrix

Axis of symmetry, hmm. See how the bowl is the same exact shape on both sides of our vertex? If we drew a VERTICAL line upwards, it would cut the bowl in half equally. An equation for a vertical line is of the form x=a. So our axis of symmetry is at x=2.

Having any trouble finding P and Q? It should be pretty straight forward, just count from the origin how many places you've moved.

10. Kagome_gurl8

p is going to equal 3,1 right?

11. Kagome_gurl8

thats what i got....

12. zepdrix

From the CENTER OF THE GRAPH, it looks like we moved 1 unit right, 1 unit up to get to P. I would call that point (1,1)

13. Kagome_gurl8

ooooooooooooooooooh

thank you so much
