From the given formulation, value of "x" can not be found.
It is why I said in my previous response
https://www.algebra.com/algebra/homework/Graphs/Graphs.faq.question.1143492.html
that the problem "makes no sense".
What can be found is the range where the values of vary.
Mathematically correct formulation is THIS :
If x varies in the domain -3 < x < 5, x=/=0, find the range of the function .
