Checking for stretch or shrink factor using (4, 4): To the casual observer, it is hard to imagine such a jump between this small percent of coverage to 100% coverage in merely 4 more days. July 316% What does B(m) mean? f(x) = 3x. Range: {0, 1}. Hence, After this point, the more coffee mugs sold, the more the positive profit; before this point, the company loses money. The equation captures the essence of the relationship succinctly and allows us to find or estimate values that are not shown on the graph. e. Profit for selling 1,000 units is equal to revenue generated by selling 1,000 units minus the total cost of making 1,000 units. Beyond 168 hours, Eduardo would be starting the next week and would start over with $9/hour for the next 40 hours.
