I haven't done inverse of rational functions before but by investinging it I think I can help.

The question is asking for the values of will the inverse function be between . This means that for the original function, the opposite is true; for which values of will the function be between . If you were to find solutions to and , and by looking at the graph you sketched you should notice that the solutions are bounds of intervals. One being and the other which should be the solutions to the question once you consider the inverse.

As I said, I haven't covered this topic so I'm not an expert as it does not appear on any of my modules (FP2 included, from AQA) + the inverse function confusion doesn't help, but hopefully it gets you going in the right direction. If you need to, use graphing software like Desmos to see what I mean. The function
