Consider the function f(x) = (1/2)x Function f has a domain of (x>0, x<0, all real numbers)
and a range of (all real numbers, y>0, y<0)
. The function (approaches y=0, approaches positive infinity, approaches negative infinity) as x increases.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
