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 < x < 4
R: -3 < y < 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.

200
What is the domain and range of the graph?
Domain: 0 < x < 5
Range: -2 < y < 0
200
Does the following represent a function? Why or why not?
No because -2 goes to both 1 and 3.
