13. write a function with a zero of 1/2. explain how you know.

The function is  

Step-by-step explanation:

If a function has a zero of .

The we can write  .

We need to work backwards to obtain the function:

We multiply through by 2 to get:

.

This implies that:

Hence a function with such zero is  

what are the statments
