## 1. Vertical Line Test -- from Wolfram MathWorld

The vertical line test is a graphical method of determining whether a curve in the plane represents the graph of a function by visually examining the number of intersections of the curve with vertical lines.

The vertical line test is a graphical method of determining whether a curve in the plane represents the graph of a function by visually examining the number of intersections of the curve with vertical lines. The motivation for the vertical line test is as follows: A relation f:A->B is a function precisely when each element x in A is matched to at most one value f(x) in B and, as a result, any vertical line in the plane can intersect the graph of a function at most once. Therefore, the...

As we saw in the previous section, functions can be represented by graphs. Graphs are useful as they display many input-output pairs in a small space and the visual information they provide can make relationships clearer. We typically construct graphs with the domain values along the horizontal axis and the range values along the vertical axis. This is because the domain values (e.g. [latex]x[/latex]) are independent and independent variables are generally associated with the horizontal axis. The values in the range are called function values and are dependent on the domain values and are therefore associated with the vertical axis.
