The answer to the first question is the first pic and the answer to the second question is the second pic.
I looked at the worked solutions but I didn't quite get it
What don't you get about them? Just showing you the answer wrong fix your understanding, it'll just help you answer this specific question. If you tell me what's bothering you, I can hopefully fill the gaps in your knowledge
For the first one, I don't understand the graph that they have drawn and for the second question, there is a lot going on so I am confused on how they got the domain of f inverse to be a/c which was before d/c for f and the part after that on the range of f note?
Thank You I totally get it now!
I was just wondering for the second question how they got the domain to be a/c? Could someone please help me with that?
Whoops, I knew I forgot something.
Remember - for an inverse function, you swap all of x and all of y. It's like taking the graph the paper is on and turning it over diagonally so you're now looking at it from the back. OF COURSE the domain might change of you do something so drastic, don't assume that it won't. However, if all of x swaps with all of y, and the domain represents all the x values, what would you expect the new domain to be?
