really? can we touch, say, y = 0, for instance?Range = y is all real numbers
review the rangeAre these answers right, and if so how do i write it in notation?
yeswould the first one be something like
(-inf, -2) U (-2,2) U (-2, inf)
were the second one correct, this would be it, alas, it isn'tand the second one is it: (-inf, inf)
