Question

Write a function with a zero of 1/2. Explain your andwer

Answer 1

A function with a zero in a is,


`f(x)=x-a`

So,



`f(x)=x-1/2`

Answer 2

f(x) = x-1/2.

Explanation:

A number n is a zero of a function if f(n)=0. In this case, if I operate 1/2 with its additive inverse we obtain zero. So, as 1/2-1/2=0 the easiest function with 1/2 as a zero will be f(x)= x-1/2. Indeed, f(1/2)=1/2-1/2=0.
