For function f(x), which condition implies a horizontal asymptote at y = 31? Limit of f (x) as x approaches 31 = infinity
Limit of f (x) as x approaches infinity = 31
Limit of f (x) as x approaches 31 plus = infinity and Limit of f (x) as x approaches 31 minus = negative infinity
Limit of f (x) as x approaches c plus = 31 andLimit of f (x) as x approaches c minus = 31 for some value of c

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.
