Find the domain of the following set:
{(2, 1) (-1, 0) (-1, 3) (0, 2) (-5, 1)}
D: {-5, -1, 0, 2}
Identify the domain and range of the following:
D: (-2, 4)
R: [-3, 3]
What is the domain and range of the following graph?
All real numbers
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.
Simplify: -2(3) + 5^2

Find the range of the following set:
{(2, 1) (-1, 0) (-1, 3) (0, 2) (-5, 1)}
R:{0, 1, 2, 3}
Identify the domain and range of the following graph:
D: (-4, 1]
R: [0, 4)
What is the domain and range of the graph?
Domain: [0, infinity)
Range: [-2, infinity)
Does the following represent a function? Why or why not?
No because -2 goes to both 1 and 3.
Simplify: 2x - 7x + 3(2x + 5)
x + 15
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}

What is the domain and range of the following?
Domain: All real numbers
Range: [-4, infinity)
Is the following a function?
No
Simplify: 2(6x - 7) - (5x +2)
7x -16
What is the domain of the following?
{2, 3, 5, 7, 9}

Identify the domain and range of the following graph using both inequalities AND interval notation.
Range: [-2] and y=-2
Domain:
(-oo,oo) and all real #s
Is the following a function?
No
Simplify: -7^2
-49

(-oo,oo)
Multiple answers
Determine the domain and range of the graph.
Domain: (-5,1]
Range: [-3,1]
What is the domain and range of the following? Hint: There is more than 1 interval.
R: (-infinity, -2] [-2, -1) (2, infinity)
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.
Simplify: (-7)^2
