Test questions will be at the end of class… Does Mrs. Ramsey have them ready? is the better question!
Unit 2: Functions
What do we need to do?
Translations First, you have to know what the parent functions look like! Parent functions…
We did this in Alg 2! Graph the parent function and move it! Ex: Left or right? Up or down? Flip or normal?
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)
Graph Exponential Example Log Example
Practice Graphing
Symmetry
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
Symmetry - algebraically
End Behavior
End Behavior Example
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)
Class Average on Unit 1 Test was ______ What did we do that was good? What do we need to change?
