Review Functions. Function A function is a special type of relation in which each element of the domain is paired with exactly one element of the range.

1 The graph represents a function because each domain value (x-value) is paired with exactly one range value (y-value). Notice that the graph is a straight.

Pattern WS

 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.

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

2 3x+4 10

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

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

 Model the function rule using a table. X2x - 7Y(x,y)

 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.

 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.

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