Best ResponseYou've already chosen the best response.1Well, if you plot those points on a graph, then move a vertical line across the graph.. If the vertical line touches more than one point at any given time, it is NOT a function.

Best ResponseYou've already chosen the best response.0A function is an association between two or more variables, such that for each and every value of the independent variables, there exists exactly one value of the dependent variable, in a specified set called the domain of the function. A function with a single independent variable, is called a single variable function. A relation is a set of ordered pairs (x, y), in a single variable relation where the x is the independent variable in a set called the domain, and y is the dependent variable in a set called the range. In order for a relation to be a function of a single independent variable, for every x there must be one and only one y. @Needsomehelpplz
