How do you graph #y =1/(x+3)#?

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#
