Is it a Function?
100
True or False-A relation is a set of ordered pairs.
What is TRUE?
100
Evaluate f(x)=-3x if x=2
What is -6?
100
Using the function f(x)=3x
find x if f(x) = 15
What is x = 5?
100
The point (1,2) is in this quadrant
What is the 1st quadrant?
100
This is reason why the points shown represent a function.
{(2, 3), (4, 5),
( -2, 6)}
What is every input has exactly one output?
200
The list of x-coordinates of a relation or a function.
What is Domain?
200
Evaluate f(x)=2x+1 if x=-2
What is -3?
200
Using the function f(x)=2x + 1
find x if f(x) = 21
What is x = 10?
200
This is the method of graphing the point (-3,4).
What is you start at the origin, go left 3 units, and then go up 4 units?
200
The results of the vertical line test to see if the graph of the points (1,3) and (1,5) represents a function.
What is NOT A FUNCTION, because the points fail the vertical line test.
300
The list of y-coordinates in a relation or a function.
What is the range?
300
Evaluate f(x)= x - 3 if x=6
What is 3?
300
Using the function f(x)=x - 3
find x if f(x) = 64
What is x = 67?
300
The signs of the coordinates in quadrant 2.
What is the (- , +)?
300
This is the reason why the table of values shown does NOT represent a function.
| x | y |
| 2 | 4 |
| 1 | 5 |
| 2 | 6 |
What is an input with more than one output?"
400
A relation that assigns exactly one input in the range to each output in the domain.
What is a function?
400
Evaluate f(x)=4x + 25 if x=5
What is 45?
400
Using the function f(x)= 4x + 25
find x if f(x) = 17
What is x = -2?
400
The quadrant that doesn't contain one of these points (-2,3), (3,-4) (2,3)
What is the third quadrant?
400
The reason why the graph shown represents a function? 
What is passing the Vertical Line Test?
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=7
What is -26?
500
Using the function f(x)= -4x + 2
find x if f(x) = -8
What is x = 2.5?
500
The quadrant that the point (0,2) is located.
What is no quadrant, because the point sits on the y-axis?
500
The reason why the graph shown does NOT represent a function? 
What is failing the Vertical Line Test?
