Agreed. I think i was confused because I got an answer that when rounded off to 1 dec place gave 0.7, so i thought it was wrong and I think I just stopped, I cant even remeber, neverthless, i'll only get one mark for the working out..I doubt i put the answer as 0.7, however, Yes! the answer is 0.7, using more than one application of halving the interval method shows this!wanton-wonton said:The root is between 0.725 and 0.75, so to one decimal place, it must be 0.7.
