How I did it:
1. Derrive f(x)
2. Recognise it to be a GP.
3. There is a limiting sum as it said 0 < x < 1, and r=-x
4. Do limiting sum formula
5. Integrate limiting sum formula to get f(x)
6. Sub in x = a and x = b

Yeah my school was supposed to replace that question since we haven't finished series and finance in time for the trials. They replaced 4 other questions but forgot this one. I can do the question now but I was seriously doubting whether I missed something from the logarithm chapters.
