Solved by pluggable solver: Plot a graph of any function AND its DOMAIN

Here's a graph of function %28x%2B9%29%2F%28x%5E2%2B16%29 ((x+9)/(x^2+16)).

The domain is shown on the x axis by a green horizontal line.






Domain:(-infinity,infinity)

x can't be 4 or -4,
since that would make g(x) infinite
All other values are OK, so
x+%3C+-4
-4+%3C+x+%3C+4
x+%3E+4
these inequalities define the domain
