The equality of the two points includes means that their coordinates are the equivalent, i.e., Multiplicating equation (2) by 2 real adds for equation (1), we get. WebbSo this is this function is 11 Because no two elements in the set they have same images. Therefore it is 11. And the range of this function, the range of this function that is 123 is also equal to pour domain that is set be. Therefore this function is onto also and since it is 11 and onto all both, therefore it will be called objective function.
