What is the range of the function defined as y=5

so... you can keep on going towards the negatives with "x", or towards the positives with "x", notice, if the "x" is negative, "y" is just a fraction, positive, but a fraction

and if "x" is positive, "y" is a positive integer
even when x =0, "y" never became 0, and is never negative either

so, the range is, "y" is always positive, but not 0, or  y>0
