Is this mapping a function and how can you tell?

• Yes its a function cause all the numbers have lines
• No it's not a function because there a 5 in both ovals
• No it's not a function because the x value 5 has y values of  2 & 9
• No it's not a function because the y value 5 has x values of  2 & 9

• No it's not a function because there are negative numbers
• No it isn't a function because an x value repeats but has different y values 
• No it isn't a function because an y value repeats but has different x values
