Linear Function vs Non Function

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.

Does this graph represent a function?

• Yes, this is a function

• No, this is not a function

Is this table a function and how can you tell?

• Yes its a function because there are not variables for missing numbers

• No it's not a function because the y value 4 repeated

• No it isn't a function because the x value 2 is repeated

• No it's not a function because the x value 5 has y values of  10 & 12

The diagram shows a linear function of g. What is the value of k.

• 5

• 4

• 7

• 8

Is the function linear or nonlinear?

• Linear Function

• Nonlinear Function

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
