Ex 2.3, 1 Which of the following relations are functions? Give reasons. If it is a function, determine its domain and range. {(2, 1), (5, 1), (8, 1), (11, 1), (14, 1), (17, 1)} The first elements are 2, 5, 8, 11, 14, and 17 . All these are not repeating. Hence, they have unique images. So, this relation is a function. Domain = Set of first elements in the pair of the function = {"2, 5, 8, 11, 14, 17" } In function, first element is not repeating Range = Set of second elements in the pair of the function = {𝟏}
