Is this set of ordered pairs a function and how can you tell?

• Yes its a function because no y values repeat
• 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

A holiday meal cost $12.50 a person plus a delivery fee of $30. Which equation represents the amount a holiday meal costs(y), including delivery, for x people?

• y = 12.50 + 30x

• y = 30 + 12.50x

• y = 12.50 + 30

• 12.50x = 30
