Best ResponseYou've already chosen the best response.1C) (1,5) the reason is your relation is pairs of number. consider the first number as x, and the second is y . your original function has x range from: 1,2,2,5 means the range is 1,5. from now on. you can say that the inverse is x is replace by y. so, in inverse function, you have y range from 1,5. and because it is inverse, the range does not depend on x value any more, but on y. so the answer is 1,5. I just want you to understand why the result is that and you can calculate by yourself in the future. Hope this help. @ some...someone. I'm sorry if I bother you. I just want to help the friend a little bit when i can.

Best ResponseYou've already chosen the best response.1@some...someone. you are right. 100% right. I don't put 2 in the middle, because it is there already when the range go from1 to 5 , it includes 2
