No restriction necessary on x, so the domain is ____________________________.
(This should be obvious).

Range? Parabola concave downward, so vertex is a maximum. Easiest to see if try to solve for the zeros and check the middle value between them.

and the exact middle of these is 0. This will mean that maximum value of the expression occurs at x=0, and the range will be all values less than or equal to , or .
