10. Graphing Square Root Functions

11. This should be the inverse of y = x2, but…
Is it a function????
This means we will only use the positive top of the graph.
(0,0)
As x goes to zero, y goes to zero. As x approaches infinity, y approaches infinity.
[0 , ∞)
[0 , ∞)
none
Increasing over time.

12. Graphing Discovery On Calc (You Try) Notes p. 5 #1-4
Use the Document Camera to fill in table, etc.

13. Any questions on those problems?

14. Graphing Cube Root Functions

15. Is this a function?? Yes! (0,0) (∞ , ∞) (∞ , ∞)
As x goes to negative infinity, y goes to negative infinity. As x approaches infinity, y approaches infinity.
(∞ , ∞)
(∞ , ∞)
About the origin (rotation)
Increasing when x > 0
Decreasing when x < 0

18. Graph by Hand using what we know now.
We know it is the square root function moved left 2 and down 4

21. Sometimes the function isn’t in a nice graphing form.
Hint: First change the following into the form. x y -4 -3 5 2 4 6
Why those x-values?

22. You Try: Put the following in graphing form. Then graph it.x y -5 -4 -3 4 -7 -5 -3 1
