Functions, Linear and Non Linear

Is this mapping a function or not a function? 

• Function

• Not a Function

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 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

Define Non-Linear Function

• A function with a 0 slope

• A function whose graph is not a straight line

• A function whose graph straight line

• A function with an undefined slope

For a function to be non-linear, it has a rate of change that varies.

• True

• False

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

• 5

• 4

• 7

• 8

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

Is the function Linear or Nonlinear?

• Linear

• Nonlinear

Is this function linear or non linear?

• Linear

• Non Linear

Where is point E located?

• ( 2, 0 )

• ( 2 , 2 )

• ( 0 , 2 )

• ( 0 , 0 )
