 $Fucntion:\ y=-x^{2\ }+4$  

Select which graph shows the function correctly graphed.

To help, you can complete the y-values (in your notebook or on a separate sheet of paper). Then, see which graph matches your (x, y) points.

CCSS.HSF-IF.C.7A

Here is the graph of $y=x^2$  

If you were to graph the line y=4, which TWO POINTS would be the solution to the system?

Click on the graph to make it larger.

(Hint: At which two points would these two graphs intersect?)

Write your answer as "(x, y) and (x, y)"
