What is the function rule being represented by this graph?
What is f(x) = x + 6
400
This word describes a relationship between two sets of numbers.
What is a relation?
400
Is this a function and WHY?
What is no, because the input "8" has two outputs.

Complete a function table for f(x) = 3x - 6
Domain: {-2, -1, 0, 1, 2}
x | f(x)
-2 --> -12
-1 --> -9
0 --> -6
1 --> -3
2 --> 0
400
Find the RANGE:
What is {-2, 2, 3, 1}
400
Graph the function.

Domain: {-1, -2, -3, -4, -5}
See boards.
500
We use this word to describe a function that spits out the same answer, regardless of the input.
Ex. f(x) = 6
What is spam?
500
Is this a function and why?
What is yes, because each input has only one output.
