Does the table represent a function?

• Yes, each input has one output

• No, an input has more than one output.

Does the mapping represent a function?

• Function, each input has one output

• Not a Function, 7 has more than one output.

• Not a Function, 8 has more than one output

• Not a Function, 9 has more than one output

Is the relation shown a function?

• YES

• NO

Is the relation a function? 
{(4,5), (4,-7), (4,2), (4,0), (4,9)}

• Yes
• No

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values
• No, because the vertical line test shows there are repeating input values
