g%28x%29=%28x%5E2-x-2%29%5E2
If you square or raise a polynomial to any non fraction power >0, you get another polynomial. The cool thing about polynomials is that their domains are "all real numbers" because there are no restricted values for x. X can be anything and the function will still be defined.
Set builder notation:
the domain is {x|x=R}
Interval notation:
the domain is (-infinity,infinity)
Infinity is written as a sideways 8.
