100
Find the domain of the following set:
{(2, 1) (-1, 0) (-1, 3) (0, 2) (-5, 1)}
D: {-5, -1, 0, 2}
100
Identify the domain and range of the following:
D: (-2,4)
R: [-3,3]
100
Does the following represent a function? Why or why not?
{(2, 1) (-1, 0) (-1, 3) (0, 2) (-5, 1)}
No, -1 has two different outputs.
100
Is the relation a function? If so, is it 1-1?
{(4,3), (2,4), (7,3), }
A function, but not 1-1.
200
Find the range of the following set:
{(2, 1) (-1, 0) (-1, 3) (0, 2) (-5, 1)}
R:{0, 1, 2, 3}
200
What is the domain and range of the graph?
Domain: [0, infinity)
Range: [-2, infinity)
200
Does the following represent a function? Why or why not?
No because -2 goes to both 1 and 3.
200
Is following graph a function? If so is it 1-1?
A 1-1 function
300
Find the domain and range of the following:
{(0, 1) (0, 2) (0, 0) (0, -2) (0, -8)}
D: {0}
R: {-8, -2, 0, 1, 2}
300
What is the domain and range of the following?
Domain: All real numbers
Range: [0, infinity)
300
Is the following a function?
No, it doesn't pass the vertical line test.
300

A function, but not 1-1.
400
What is the domain of the following?
{2, 3, 5, 7, 9}
400
What the domain and range of the following?
D: [-2 , 6] R: [-6 , 2]
400
Is the following a function?
No, it doesn't pass the vertical line test.
400

(-oo,oo)
Multiple answers
500
Identify the domain and range of the following graph.
Range: {2}
Domain: All real numbers
500
Is the following a function? Why or why not?
Yes. Every input has only one output. The holes in the graph make it so that no x values will repeat.
500
Identify the domain and range of the following graph.
Yes, it passes the vertical line test, but it is not 1- to -1
