According to the rational root theorem, is a potential rational root of which function? f(x) = 4x4 – 7x2 + x + 25 f(x) = 9x4 – 7x2 + x + 10 f(x) = 10x4 – 7x2 + x + 9 f(x) = 25x4 – 7x2 + x + 4

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.
