Evaluating Functions
True or False
Domain and Range
Function or Not?
100
The connection between two pieces of data, often represented as ordered pairs, in a table, a mapping, or on a graph.
What is A RELATION?
100
Evaluate f(x)=-3x if x=2
What is -6?
100
All relations are also functions.
What is FALSE, because functions must have exactly one output for each input, and relations do not require that?
100
State the domain of the function {(4,-2),(-1,1),(2,-3),(3,0)}
What is {4,-1,2,3}?
100
Is it a function?
{(2, 3), (4, 5), ( -2, 6)}
What is YES because x does not repeat?
200
The first set of values in the ordered pairs of a relation or a function. (x-values)
What is the INPUT / DOMAIN?
200
Evaluate f(x)=2x+1 if x=-2
What is -3?
200
When creating a mapping, I write the domains and ranges from least to greatest, with repeats, and draw arrows between the paired values.
What is FALSE, because when creating mappings, there are no repeats?
200
State the range of the function {(4,-2),(-1,1),(2,-3),(3,0)}
What is {-2,1,-3,0}?
200
Is it a function?
What is NO, the x-values repeat (x=2 has two outputs)?
300
The second set of values in the ordered pairs of a relation or a function. (y-values)
What is the OUTPUT / RANGE?
300
Evaluate f(x)= -3 - 2x if x=6
What is -15?
300
The only ways to represent a relation are with 1) a table, 2) a mapping, or 3) a graph.
What is FALSE, because coordinate pairs also represent relations?
300
Find the domain and range of {(-1,5),(2,3),(4,2),(-1,2)}
What is a domain of {-1,2,4} and a range of {5,3,2}?
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) - 5 if x=5
What is 0?
400
In an experiment where you're testing how the amount of sunlight affects a plant's growth, the plant's growth is the independent variable.
What is FALSE, the amount of sunlight is the independent variable?
400
Find the domain and range of {(-3,4),(0,10),(11,8),(4,5)}
What is a domain of {-3,0,11,4} and a range of {4,10,8,5}?
400
Is it a function? 
What is YES because it passes the Vertical Line Test?
500
The visual test to see if a graph is a function.
What is the VERTICAL LINE TEST?
500
Evaluate f(x)=-(4x+2) if x=7
What is -30?
500
If you're studying how the number of hours a student studies impacts their test score, the number of hours studied is the dependent variable.
What is FALSE, the number of hours studied is the independent variable?
500
Find the domain and range of {(-5,8),(-5,4),(6,9),(3,10)}
What is a domain of {-5,6,3} and a range of {8,4,9,10}?
500
Is it a function? 
What is NO because it does not pass the Vertical Line Test?
