Is this table a function or not a function?

• Function because each input has on output

• Not a Function because each input has more than one output

• Not a function because there is a -2 and a positive 2

• Function because each input has more than one output

Is the graph proportional or non-proportional and why?

• Proportional, the graphed line goes through the origin

• Proportional, The graphed line has a positive slope

• Non-proportional, the graphed line does not go through the origin
