What is the domain and range of the quadratic equation y = (x – 5)^2 + 10?

OpenStudy (anonymous):

Domain is all real numbers (all quadratics have all real numbers for a domain) Range is y ≥ 10

The vertex is (5,10) and the parabola opens up (as there is no - sign in front of the x term) so the range has to be greater than that.
