Objective [1.4]-Problems Choose symbols and write out functional notation for a “functional” relationship (i.e. function) For each functional relationship statement identify the input and output and define appropriate symbols(letters) for each. Then define a symbol(letter) for the functional relationship and write out the relationship in functional notation. Also “retranslate” back into English using the symbols and then all in English using the word “function” Note: In general x, y, and f are not appropriate choices. Also, symbols choices will vary from person to person but as long they are defined it is fine. Example: “There is a relationship between time and average price of a home Solution: Define: Input: Let “time” be t . Output: Let “average home price be” be p. Relationship: Let the functional relationship be H Functional Notation: p=H(t) English: “p is a function, H, of t” or just “p is a function of t” “average home price is a function of time”
