Let d be the domain and let ƒ be the possible function. determine if the relation is an example of a function. "d = {x| x is a person’s social security number} ƒ(x) = the person’s name. a. no. at least one output results in two inputs. b. yes. one input results in one output. c. yes. one output results in one input. d. no. at least one input results in two outputs."

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
