Set P = {-2,0,2} and the remaining elements are { (-2,-2), (-2,2), (0,-2), (0,0), (2,-2), (2,0), (2,2)} 2. /Pages 3 0 R To determine whether a given relation is a function or not, one needs first to find out the input values, then the output values. The value of a new car in dollars is given by the function \(V(t) = 1,800t + 22,000\) where \(t\) represents the age of the car in years. If the function is f (x)= 6x-27, and the domain is {-5, 3, 15, 17}, then find the range. Worksheet 4.1 Relations and Functions Write each of the following as a relation, state the domain and range, then determine if it is a function. With the definition of a function comes special notation. 26 13

Given a function rule, students will complete a table of values or given a table of values, students will find the function rule.Worksheet 4: Function rules and table of values 2Riddle. Consider the relations consisting of the seven ordered pair solutions to \(y = |x| 2 \)and \(x = |y| + 1\). Who is credited with the introduction of the notation \(y = f (x)\)? These multiple representation tasks help students see the connections between the equation, table of values, and graph. Function. Here we are asked to find the x-value given a particular y-value. Find \(x\) where \(g (x) = 0, g (x) = 1\), and \(g (x) = 4\). There is then practice on these topics. \(g (2) = 5, g (3) = 4\) and \(g (1) = 4 , g (5) = 4\) and \(g (1) = 4\), 7.
