Identifying Functions of Tables Graph and Mapping

Which set of ordered pairs is not a function? (select all that apply)

• {(9, 5), (10, 5), (-9, 5), (-10, -5)}

• {(3, 4), (4, -3), (7, 4), (-3, 4)}

• {(6, -5), (7, -3), (6, -1), (9, 1)}

• {(2, -2), (5, 9), (5, -7), (1, 4)}

Which of these tables represent a function? (A to D from top to bottom)

• A

• B

• C

• D

How do you use the vertical line test?

• Draw vertical lines through your graph. If any of the vertical lines you draw intersects the graph more than once then the graph is not the graph of a function.

• Draw vertical lines through your graph. If any of the vertical lines you draw intersects the graph more than once, then it is a function.

What is the definition of a function?

• Has inputs and outputs

• Inputs have different outputs every time

• x-values and

  y-values

• Every input has only one output

Select all relations that are functions from the choices.

• A

• B

• C

• D

Select all of the values of x so that g(x) is NOT a function

• A. 3

• B. 6

• C. 9

• D. 10

Does the graph represent a FUNCTION?

• Yes

• No

Which table represents a relationships that is NOT a FUNCTION?

• Q

• R

• S

• T

True or False

• True

• False

Determine if the two tables are show a function relationship.

• Both Tables 1 and 2 shows Function relation.

• Both Tables 1 and 2 does not show Function relation.

• Only Table 1 shows Function Relation but, Table 2 does not show Function Relation.

• Only Table 1 does not show a Function relation but, Table 2 shows a Function Relation.
