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 < 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.
100
What is the slope of the line given these two points?
(-2,4) and (6,-8)
m=-3/2
100
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.
200
Identify the SLOPE and Y-INTERCEPT in the following:
y=3/2x-8
m= 3/2
b= -8
200
What is f(5)?
f(5) = 4
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

Domain:(-3, 8]
Range: (-4.5,2.5]
( I'll accept -5 and 3)
300
Is the following a function?
No, it doesn't pass the vertical line test.
300
Rewrite the following in slope intercept form:
12x+4y=36
y=-3x+9
300
g(x) = x2 -3x + 4

y=-4/10x+8
y= -2/5x+8
400
f(x) = 4|x| - 6

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.
500
What is the slope of the given graph?
m=4/3
500
