Which graph does NOT pass the vertical line test?

• Graph 1

• Graph 2

• Graph 3

• Graph 4

Is this graph a function or not a function? 

• Function 

• Not a Function 

What is the definition of a FUNCTION?

• Has inputs and outputs

• A relation where every input has only ONE output

• a relationship between variables

Is this function linear or nonlinear?

• Linear function

• Nonlinear function

Which ordered pair is a solution of
the equation
y = 6x?

• (12, 2)

• (4, 18)

• (3, 18)

• (6, 1)

Is this a function? 

• Yes

• No

Does this mapping diagram represent a function?

• No, because there are repeating input values

• Yes, because there are no 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.
