• Question 1
300 seconds
Q. For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain.
Remember:  Domain is x
(x,y)
D: {1, -3, -4,}
R: {0, 1, 2, -4}
D:{0, 1, 2, -4}
R:{1, -3, -4}
D:{0, 1, 2, 3, 4}
R:{1, -3, -4}
• Question 2
900 seconds Q. What is the range of the graph?
Remember: Range is y!
1 ≤ x ≤ 5
1 < x < 5
1 ≤ y ≤ 5
1 < y < 5
• Question 3
900 seconds Q. What is the domain of the graph?
Remember:  Domain is x
1≤ x ≤ 4
1 < x < 4
1≤ y ≤ 4
1 < y < 4
• Question 4
900 seconds Q. Does the graph represent a function?
If you have an x value that has 2 "y" values it is NOT a function!
Yes, because the vertical line test shows there are no repeating input values
No, because the vertical line test shows there are repeating input values
• Question 5
30 seconds Q. Which graph does NOT pass the vertical line test?
Graph 1
Graph 2
Graph 3
Graph 4
• Question 6
30 seconds
Q. All of the y values or outputs are called what?
Domain
Range
• Question 7
30 seconds
Q. All of the x values or inputs are called what?
Domain
Range
• Question 8
900 seconds
Q. What is the range of the following relation:
(9, -2) (4, 3)  ( 8, 10) ( -4, 8)
Range is the y values
(x,y)
-4, 4, 8, 9
-2, 3, 8, 10
(9, -2) ( 4, 3)
(8, 10) (-4, 8)
• Question 9
900 seconds Q. Identify the domain of the following relation:
Remember domain is the "x" values
-6, 14, 2, 28
(-6,14), (0,32), (2,38), (4,44)
-6, 0, 2, 4
14, 32, 38, 44
• Question 10
120 seconds Q. What is the domain of the graph?
Remember:   Domain is the "x" values from left to right
-7 ≤ x < 5
-3 ≤ x < 1
-3 ≤ y < 1
-7 ≤ y < 5
• Question 11
120 seconds Q. What is the range of the graph?
Remember: Range is the "y" values (up and down)
-7 ≤ x < 5
-3 ≤ x < 1
-3 ≤ y < 1
-7 ≤ y < 5
• Question 12
120 seconds Q. What is the range?
Remember range is the "y" values (up and down)
And an open circle means it DOES NOT equal that number - use < and >
Only use ≤ and ≥ with a closed circle.
-4 < x ≤ 5
-4 ≤ x < 5
-3 < y < 3
-3 ≤ y ≤ 3
• Question 13
120 seconds Q. What is the domain?
Remember domain is the "x" values.
And an open circle means it DOES NOT equal that number - use < and >
Only use ≤ and ≥ with a closed circle.
-4 < x ≤ 5
-4 ≤ x < 5
-3 < y < 3
-3 ≤ y ≤ 3
• Question 14

The cat has 2 eyes
The cat has 2 kittens
The cat has 4 paws
The cat weights 5.4 kg
• Question 15

Remember DOMAIN is "x" values that go left to right.
-4 ≤ x ≤ 3
-1 ≤ x ≤ 4
4 < x < 3
-1 < x < 4
• Question 16
