hi for (b) u should find the interval image of by
Originally Posted by Raoh hi for (b) u should find the interval image of by and that depends on , if is increasing the interval image must be . if is decreasing the interval must be . hope that's right..
Originally Posted by Raoh and that depends on , if is increasing the interval image must be . if is decreasing the interval must be . hope that's right.. thank you Raoh , can you help for ii) ?
for ii) is it ?
