1/4
Which number is NOT an element in the domain of this relation?
{ (−2, 3), (0, 4), (1, 1), (6, 0) }
–2
Cheer up!
2/4
Which graph appears to be a function?
Cheer up!
3/4
A relation is shown in the table, where x represents the independent variable, and y represents the dependent variable. Could this table represent a function?
No
Yes
4/4
A part of a quadratic function f is graphed on the coordinate plane. What is the domain of the part of the function shown?
all real numbers greater than or equal to –1
all real numbers greater than or equal to 1
all real numbers
all real numbers greater than or equal to –1 and less than or equal to 3

Try again
1 is the domain of the point (1,1).
Try again
The arrow points up to the right, so the x-value will continue increasing beyond 3.
Try again
A function has only 1 y-value for each x-value. Here, some x-values have more than 1 y-value. For example, (2,1) and (2,3).
Correct!
This is the graph of a function because every x-value has only 1 y-value.
correct!
The graph begins at –1 and keeps going to the right forever.
Try again
0 is the domain of (0,4).
Try again
All real numbers greater than or equal to 1 is the range. The domain is the x-values from left to right.
Try again
The domain only includes the x-values that have corresponding y-values on the graph. The domain begins at –1 and goes to the right.
Try again
A function has only 1 y-value for each x-value. Here, some x-values have more than 1 y-value. For example, (0,4) and (0,-4).
way to go!
4 is not an x-value, so it is not an element of the domain.
Try again
A function has only 1 y-value for each x-value. Here, some x-values have more than 1 y-value. For example, (3,2) and (3,–4).
Try again
Every input has exactly one output. The point (4,12) is listed in the table twice, but every time you input a 4, the output is 12.
Correct!
This is a function because every input has exactly one output.
Try again
–2 is the domain of (–2,3).
