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

anonymous · Answer

Idk, Functions are seriously throwing me for a loop right now.

baldymcgee6 · Answer

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

anonymous · Answer

I've heard of it but I can't recall exactly what it is.

baldymcgee6 · Answer

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.

anonymous · Answer

Okay so it is 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.
