In problems 3 and 5 we looked at and plotted two important trends: the function values jf(xn)j and the absolute error jxn xj of the iterates. it is probably clear why the absolute error, jxn , decays to zero as the iterates converge to the true answer. must the function values jf(xn)j also decay to zero? why or why not? answer yes or no, and write a sentence or two justifying your answer.

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.
