CCSS.8.F.A.1

If a graph represents a function, it should be able to pass a

_________ line test.

• curvy

• horizonal

• straight

• vertical

Passing the vertical line test means that any vertical

line drawn on the graph should intersect the graph at exactly ______ point.

• one

• two

• zero

• several

The table represents a function.

• yes, because each output has one input

• Yes, because each input has only one output

• no, because the outputs repeat

• no, because inputs and outputs repeat

CCSS.8.F.A.1

This graph is a function.

• yes, it passes the vertical line test

• yes, it passes the horizontal line test

• yes, it passes the straight line test

• no, it does not pass the line test

The graph is a function because it passes the vertical line test.

• true

• false

This set of ordered pairs represents a function.

• yes, because each input has one unique output

• no, because each input does not have one unique output

• yes, because the -2 repeats

• no, because one ordered pair has a zero for the input
