You can put this solution on YOUR website!
The domain of the function is all x values where f(x) is defined.
In this case, any division by zero would be undefined. Or when,
x%5E2-x-2=0
%28x-2%29%28x%2B1%29=0 Factor the equation.
with solutions x=2 and x=-1.
So the domain is any x except x=2 and x=-1.
