Answer:
Domain ={1,2,3,4}
Range = {2,3,4}
Step-by-step explanation:
Domain : It is the set of values , for which our x is defined for. In the tabular form, all the values on side of x are the Domain of the function. Hence Domain ={1,2,3,4}
Range : It is the set of values to which the function results into for the domain. In Tabular form the values which comes under the head of y are the range. Duplicate values are taken only for once. Hence
Range = {2,3,4}
