• Vertical Translation Down 3 units

• Vertical Translation Up 8/3 units

• Vertical Translation Down 8/3 units

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

• Function

• Not a Function

Is this is a function or not a function?
