 Hi and welcome to the session. Let us discuss the following question today. Question is state with reason whether the following functions have inverse. H is a function from set 2, 3, 4, 5 to set 7, 9, 11, 13. If H is equal to set of ordered pairs of 2, 7, 3, 9, 4, 11, 5, 13. Let us run the solution now. We are given H is a function from set 2, 3, 4, H is equal to set of ordered pairs of distinct images in the set 7, 9, 11, 13. So, clearly it is a 1, 1 function. Also, imagine the set 2, 3, 4, 5. Or we can say all the elements of the set 7, 9, 11, 13 are the image of the some element of the set 2, 3, 4, 5. Can write H is inverse. The answer is yes. H has inverse. Since H is inverse, complete the session. Hope you understood the session. Take care and goodbye.
