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.

The graph shows Cindy going for a bike ride. When does she stop to take a break?
She stops at 12 minutes for a total of 3 minutes.

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: 0 <= x < infinity
Range: -2 <= y < infinity
200
Does the following represent a function? Why or why not?
No because -2 goes to both 1 and 3.
200
What is Dave doing at 14 minutes?
He is stopped.
200
What is f(5)?
f(5) = 4
300
Find the domain and range of the following:
y=x2+4
D: (-inf.,+inf)
R: [4, inf)
300
What is the domain and range of the following?
Domain: -infinity < x < infinity
Range: -4 <= y < infinity
300
Is the following a function?
No, it doesn't pass the vertical line test.

g(x) = x2 -3x + 4
What is g(3)?
g(3) = 4
400
What is the domain of the following?
{2, 3, 5, 7, 9}
400
What the domain and range of the following?
D: -2 <= x <= 6 R: -6 <= y <= 2
400
Is the following a function?
No, it doesn't pass the vertical line test.
400
f(x) = 4|x| - 6
g(x) = -2x +7
What is f(-3) - g(1)?
f(-3) - g(1) = 1
500
Draw a graph with a range of 2 < y < 5 and a domain of
(-oo,oo)
Multiple answers
500
Identify the domain and range of the following graph.
Range: y=-2
Domain: -infinity < x < inifinity
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
g(x) = 0.5x - 4
What is g(2y - 4)?
g(2y - 4) = y - 6
