Which of the following statements describes whether or not y2=9x+1 is a function?
The relation is a function because each output value has only one input value.
The relation is not a function because several inputs have more than one output.
The relation is a function because a quadratic equation represents the relation and all quadratic relations are functions.
The relation is not a function because a square root equation represents the relation and all square root relations are not functions.
Which of the following relations is a function?
A. {(8, 3), (8, 0), (-8, 13), (-8, 17)}
B. {(5, 9), (-7, 3), (-5, 11), (7, 9)}
C. {(-12, 1), (4, 9), (-12, 8), (-4, 15)}
D. {(6, 11), (-8, 7), (6, 4), (9, 5)}
Which of the following strategies could be used to show why the equation x2+y2=4 is not a function?

Fill in a value for y and solve for x.
Fill in values for x and y until a pair is found where x2+y2 does equal 4.
Fill in values for x and y until a pair is found where x2+y2 does not equal 4.
Which of the following equations generates the graph of a function?

B. y2=x
C. Both y=x and y2=x
D. Neither y=x nor y2=x
The graph below shows a relation and four lines j, k, m, and n. Which statement explains whether or not the relation is a function?
The relation is a function because line j only intersects the graph of the relation once.
The relation is a function because line n only intersects the graph of the relation once.
The relation is not a function because line k intersects the graph of the relation more than once.
The relation is not a function because line m intersects the graph of the relation more than once.
Two relations are shown below. Which relations are functions?
A. I only
B. II only
C. both I and II
D. neither I nor II
Four graphs are shown below. Which of the graphs represent functions?
I only
I and II only
I, II, and IV only
II, III, and IV only
