Relations and Functions

Determine if the relation is a function

• Not a function, each input has more than one output

• Yes it is a function, because each input has exactly on output

• Not a function, input is equal to output

• Yes it is a function, -1/2 is a fraction of 2

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
