True or False-A relation is a set of ordered pairs
What is TRUE?
100
Evaluate f(x)=-3x-x if x=2
What is -8?
100
Given the points of a function: (0,-2);(1,-1); (2,0), state the domain
What are {0, 1, & 2}?
100
The point (1,2) is in this quadrant
What is the 1st quadrant?
100
Is it a function?
{(2, 3), (4, 5), ( -2, 6)}
What is YES because x does not repeat?
200
The set of inputs of a relation or a function
What is Domain?
200
Evaluate f(x)=.75x+1 if x=-2
What is -.5?
200
Given the points of a function , (0,0); (1,3); (2,6), state the range.
What is {0, 3, and 6}?
200
How do you graph the point (-3,4)?
What is you go left 3 units on the x-axis then go up 4 units on the y-axis?
200
Using the vertical line test does the graph of the points (1,3) and (1,5) represent a function?
What is False, the points fail the vertical line test
300
The set of outputs in a relation or a function
What is the range?
300
Evaluate f(x)=-3 - x if x=6-x
What is x-9?
300
The range is greater than -9 and less than 5. Write it as an inequality.
What is -9<y<5?
300
The signs of the points in quadrant 2
What is the (- , +)?
300
Is it a function?
| x | y |
| 2 | 4 |
| 1 | 5 |
| 2 | 6 |
What is NO because x repeats?
400
A relation that assigns exactly one value in the range to each value in the domain?
What is a function?
400
Evaluate f(x)=25 + 4x if x=x+5
What is 4x+45?
400
The domain is all real numbers greater than -3. Write this in interval notation or inequality notation.
What is x>-3 or (-3, inf.)?

500
The test to tell if a graph is a function
What is the Vertical Line Test?
500
Evaluate f(x)=-(4x+2) if x=x-7
What is -4x+26
500
Draw a function that would have domain of all real numbers and a range of of -4 or more.
I have to see your graph
500
What quadrant is the point (0,2) in?
What is none because the point sits on the y-axis
500
Is it a function?
What is NO because it does not pass the Vertical Line Test?
