Q1_General Mathematics SHSModule 1Lesson1Representing Real-LifeSituations Using FunctionsWelcome to the first lesson of your General Mathematics. This lesson will give youthe practical application of functions in a real-life scenario including the piece-wisefunction. When you are in Grade 8, you already encountered relation and function. But in this module, let’s take into a deeper sense on how this topic can be useful inour daily life. Are you all ready?What’s InBefore we proceed in representing real-life scenario using function, let’s go back towhere we start. What have you remembered about relations and functions?A relation is any set of ordered pairs. The set of all first elements of the orderedpairs is called the domain of the relation, and the set of all second elements is calledthe range. A function is a relation or rule of correspondence between two elements (domainand range) such that each element in the domain corresponds to exactly one elementin the range. To further understand function, let’s study the following. Given the following ordered pairs, which relations are functions?A = {(1,2), (2,3), (3,4), (4,5)}B = {(3,3), (4,4), (5,5), (6,6)}C = {(1,0), (0, 1, (-1,0), (0,-1)}D = {(a, b), (b, c), (c, d), (a, d)}

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
