#### Answer:

This is a polynomical function, so, its domain will be all the real domain.

#### Explanation:

A polynomical function has as domain all the real line because it has no discontinuity points. There are no points whose image is

In you case you have a polynomical function of second degree, a parabola, so, its domain is the full real line.
