The numbers within the sets of parentheses come before each element. What do the different brackets mean in terms of domain and range in this regard? We can determine the number of turning points of the function (the number of times the graph turned). Relation: There is a relationship between two variables. So our domain is going to be all values of x. Follow the format, it is customary not to repeat numbers and to put numbers in numerical order. The domain of a function is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. The domain of a graph is made up of all the input values shown on the x-axis because the domain refers to the set of possible input values.
