Do the set of integers between 50 and 70 make up the "co-domain" or the "range"?

The codomain is the set of potential (or, permitted) elements of the right column, based solely on the initial description of the function, in this case "integers between 50 and 70".

The range is the set of actual elements of the right column (that is, outputs obtained from inputs in the domain).
