(6,1),(7,2),(8,3)
{ 6, 7, 8 }
100
What is the Range of the graph?
-2 _< Y < 1
100
List the intervals when the graph is increasing and decreasing.
HINT: Arrow means its continuous.. aka infinite.. 
DECREASES: (-infinity, 1)
INCREASES: (1, infinity)
100
What function is this? 
LINEAR Absolute Value function
200
This word is used to describe the set of all outputs of a function | All Y values of a graph
Range
200
Is the following line a function?
Yes, it is a function
200
What is the DOMAIN of the graph?
- infinity < x <_ 1
200
Find the RANGE in
{-6, -5, -2, 3, 5}
200
TRUE OR FALSE: The graph only decreases..svg?revision=1&size=bestfit&width=300&height=300)
FALSE!
200
What function is this?
Linear function
300
Complete the statement: In order for a graph to be a ______, __ does not ___.
In order for a graph to be a function, X does not REPEAT
300
Is this a function and why?
Not a function, because x's repeat at 8
300
True or False: The DOMAIN of the graph is {1, 4, 5, 6}.
FALSE
300
Find DOMAIN and RANGE:
D={-1 ≤ x ≤ 4}
R={-4 ≤ y ≤ 5}
300
In order, when is it increasing/decreasing/constant in the graph?
Decreases first, increases after
300
What function is this?
Exponential function
400
What visual test can be used to determine if a graph is a function, from left to right?
EXTRA 100: How many points should the vertical line test cross the graph for it to be a function?
Vertical Line Test | Pencil Test
Bonus 100: One point
400
Does the following table represent a function?
x f(x)
1 2
2 5
6 2
2 9
5 1
No, because the input (x) of 2 has two different outputs (y)
400
