Question 919776
Domain of a function y = f(x) is the set of possible x-values such that y is defined. In this case the domain is the set of all real numbers. The range is the set of all possible values for y (the image). Since -x^2 must be non-positive for real x, the range is (-infinity, 0]. (the ] indicating that 0 is included)


y = -x^2 is a continuous function everywhere.
