this is quadratic function (parabola, common view of equation is y=ax²+bx+c).
Domain: The function exists in all the points. It means, that x∈R or x∈(-oo;+oo).
Range: according to the common view a>0, it means, that parabola has 'min' in its vertice (x₀=-1). Range is y∈[4;+oo) or y≥4.

Step-by-step explanation:
(Interpreting equation as)
We can reduce the fraction by dividing the top and the bottom by terms they have in common.
First, lets rewrite both the numerator and denominator in terms of each other.
If you expand the fraction, you will get exactly what you start with, now this is fine.
As we can see both halves of the fraction have a common term (), so we can divide by this - and the fraction will still be equivalent to as it was before
