Is It a Function Tables Coordinates Mapping

Which of the following represents a function?

• <(1,2), (1,3), (1,4), (1,5)>

• <(1,2), (2,3), (3,4), (4,5)>

• <(1,2), (3,4), (3,5), (6,7)>

• <(1,2), (3,4), (5,6), (5,8)>

Which of the tables represents a function?

• Table A

• Table B

• Both Tables A & B represent functions

• Neither table represents a function

Which of the following represent a function? (Pick 2)

• {(9,-7), (7,-5), (4,-2), (3, -8)}

• {(3,5), (4,6), (5,7), (4,8)}

• {(6,3), (4,9), (-2,-7), (-8,-5)}

• {(-2,0), (0,3), (4,5), (0,7)}

Does this mapping represent a function?

• No, because two inputs map to 0

• No, because two inputs map to 1

• Yes, because 0 maps to 0 and 1 maps to 1

• No, because the inputs can result in more than one output

Does this mapping diagram represent a function?

• No, because an input value goes to multiple output values

• Yes, because each input goes to one and only one output

A table organizing the input, rule and output of a function is called a ______ ______?

• function table

• ordered pair

• linear function
