    What is the common "function test" we can use to check?

    Well, we can use something called the vertical line test... Have you heard of this?

    Well, 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.

    A 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
