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.

f(x) = 3x + 4
Find f(2).
f(2) = 10
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: x<=0
Range: y<=-2
200
Does the following represent a function? Why or why not?
No because -2 goes to both 1 and 3.

The total cost in dollars to buy uniforms for the players on a volleyball team can be found using the function c = 34.95u + 6.25, where u is the number of uniforms bought. If there are at least 8 players but not more than 12 players on the volleyball team, what is the domain of the function for this situation?
{8, 9, 10, 11, 12}

Identify the domain and range of the following graph.
Range: y=-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.
