1. Blue Day – 1/21/2015 Gold Day – 1/22/2015

2. Pattern WS

3.  Study of functions  Patterns  Functions machines  Function notations  Friday, 1/23/2015 is the last day of progress reporting period.  All work needs to be in by Thursday, 1/22/2015.

4. f (x) = 3x+4 Name of the Function Tells what number to plug into the function The function

5. 2 3x+4 10

6.  There are 3 ways you will usually see functions  Rules  Tables  Graphs

7.  Model the function rule using a table. X-3xY(x,y) 0 1 2 3

8.  Model the function rule using a table. X2x - 7Y(x,y) 0 1 2 3

9.  Use the points from the table in example 1 to model as a graph X-3xY(x,y) 0-3(0)0(0,0) 1-3(1)-3(1,-3) 2-3(2)-6(2,-6) 3-3(3)-9(3,-9) **Join the points to form a line.

10.  Use the points from the table in example 2 to model as a graph X2x - 7Y(x,y) 02(0)-7-7(0,-7) 12(1)-7-5(1,-5) 22(2)-7-3(2,-3) 32(3)-7(3,-1) **Join the points to form a line.

16.  What is the domain and range of the following graphs?
