f(4)=19; f(6)=39; f(8)=67. No other values for the domain are given so the range is { 19,39,67}, the set of values generated by all the values of the domain. Another interpretation of the range can be the minimum and maximum values of the function, in which case these would be 19 and 67, but the strict definition of range is the set of values generated by the domain.
