Determine If It Is a Function

Which graph does NOT pass the vertical line test?

• Graph 1

• Graph 2

• Graph 3

• Graph 4

Is the following graph a linear function?

• It is a line, therefore it is a linear function.

• It is not a linear function because vertical lines aren't functions.

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.

Is this table a function or not a function? 

• Function

• Not a Function 

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

Is this a function? Explain.

• Yes; it passes the horizontal line test.

• No; it is not a straight line.

• Yes; it passes the vertical line test.

• No; there is a line connecting the dots.
