Looking at Functions in Table Form Algebra

Is the relation a function? Explain.

• Yes, the x-value 11 has two y-values paired with it.

• Yes, each x-value has only one y-value paired with it.

• No, the x-value 11 has two y-values paired with it.

• No, each x-value has only one y-value paired with it.

The table represents the equation k = j - 20.

Use the equation to find the missing value.

• 34

• 27

• 41

• 38

Does the following relation represent a function?

(1,5), (1,6), (1,7), (1,8), (1,9)

• Yes, there are no repeated x-values

• No, there are repeated x-values

• A
• B
• C
• D

Is this table a function or not a function? 

• Function

• Not a Function

Does the mapping represent a function?

• Yes

• No

Which of the following equations describes the relationship between a and b?

• b = a +13

• b = a +5

• b = a +18

• b = a +14

Does the graph represent a function?

• Yes

• No

Is the following relation a function: (2, 3) (4, 5) (5, 3)

• yes because one output for each input

• no because 3 appears twice as an output

• not enough information

• it depends

Is the following relation a function: (2, 3) (2, 4) (5, 10)

• yes because one input for each output

• no because 2 appears twice as an input with different outputs

• not enough information

• it depends
