Explain the difference between a relation and a function.

• A relation is a special type of function, while a function is a set of ordered pairs.

• A relation is a one-to-one mapping, while a function can have multiple outputs for the same input.

• A relation is always linear, while a function can be non-linear.

• A relation is a set of ordered pairs, while a function is a special type of relation where each input has only one output.

Given the following graph, determine if the relation is a function:

• Function

• Not a function

Which relation is NOT a function?

• {(1,-5), (3,1), (-5,4), (4,-2)}

• {(2,7), (3,7), (4,7), (5,8)}

• {(1,-5), (-1,6), (1,5), (6,-3)}

• {(3,-2), (5,-6), (7,7), (8,8)}

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.
