1. Test questions will be at the end of class…
Does Mrs. Ramsey have them ready? is the better question! 

2. Unit 2: Functions

3. What do we need to do?

4. Translations
First, you have to know what the parent functions look like!
Parent functions…

7. We did this in Alg 2! Graph the parent function and move it! Ex:
Left or right?
Up or down?
Flip or normal?

8. New to Pre-Calc…
-f(x)
If there is a negative in the front it is a reflection over the x-axis. (flip)
f(-x)
If there is a negative on the “inside” it is a reflection over the y-axis. (mirror imaged)

9. Graph
Exponential Example
Log Example

10. Practice Graphing

11. Symmetry

12. Symmetry - Examples w/ respect to the y-axis (EVEN)
f(x) = x2
w/ respect to the x-axis (ODD)
x = y2
w/ respect to the origin
f(x) = x3

15. Symmetry - algebraically

16. End Behavior

17. End Behavior Example

19. Homework P. 99 (47-54, 63-66 state end behavior using limits too)
p. 109 (29-31 no calc…just graph, 35, 38, 39, 41)

20. Class Average on Unit 1 Test was ______
What did we do that was good?
What do we need to change?
