Functions and Relations Review

Is this graph a function and how can you tell?

• Yes its a function cause it doesn't cross itself
• No it's not a function because it goes through the origin
• No it's not a function because the x value 4 has y values of  -2 & 2
• No it's not a function because the y value 4 has x values of  -2 & 2

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values
• No, because the vertical line test shows there are repeating input values

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.
