For the function, f(x)=(9x+7)/(2x+4)
a. find the critical points or explain, with a derivative, why there are no critical points.
b. find the x and y coordinates of the absolute maximum and absolute minimum of f(x) in the interval [-10, 7]. be sure to show all the necessary supporting calculus.
c. find the x and y coordinates of the absolute maximum and absolute minimum of f(x) in the interval [0, 5]. be sure to show all the necessary supporting calculus.

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.

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18}, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.
