Find the domain of this function and solve the function for numbers around the restriction.
Explanation:
First of all, you know that this function has a domain restriction, since no number can be divided by zero. Therefore, find the result of
You'll see that, for this function, x cannot be 2 or -2. You can then solve the function for some numbers around 2 and -2 and connect them with lines. There will be 3 intervals. For example:
graph{x/(x^2-4) [-10, 10, -5, 5]}
