Solve the function for numbers around x=3, since that is the domain function. Then connect the results you find, forming two curves.

Explanation:

This is a reciprocal function , so it has a domain restriction. Since no number can be divided by zero, we have to find the solution for x+3=0. That would be 3.
After that, we solve the function for numbers close to the restriction. The result should be two curves.
f(6)=0.333
f(5)=0.5
f(4)=1

f(2)=1
f(1)=0.5
f(0)=0.333
