Given {(-5,2), (-3,1), (0,4), (0,5), (1,6)}...

• This is a function and the domain is -5, -3, 0, 1
• This is a function and the domain is 2, 1, 4, 5, 6
• This is not a function and the domain is 2, 1, 4, 5, 6
• This is not a function and the domain is -5,-3,0,1

Using the diagram find the best description of the mapping. 

• This is not a function because -2 has two outputs
• This is a function since the outputs do not repeat
• this is not a function because there is a zero in the input
• Not enough information is given to determine whether or not this is a function

CCSS.8.F.A.1

Using the diagram find the best description of the mapping. 

• This is not a function because both -1 and 1 map to 5
• This is a function since the domain values increase by 1
• this is not a function because there is a zero in the input
• This is a function since all of the input values have unique output values
