HOMEWORK QUIZ (2.1A) Use for 1-2: Age 1 4 18 27 35 40 44 45 (years ) Cost 45 45 45 64 68 90 90 125 ($) 1. Is cost a function of age REMEMBER: “y equals f of x” The function displayed in the table above is: Cost = f(age) You know this because each age value represents one cost value Answer (“A”): Yes, since the age has only one cost 2. Is age a function of cost As seen above, the function here is: Cost =f(age) The function, Age = f(cost) is not possible in the case of this table. If that were the correct function, then: f(45) = 1, f(45) = 14, and f(45) = 18 OR f(45) = 1 = 14 = 18 Since the function is the same in each case above, this is impossib
