If you understand the definition of a mathematical function, a good way to judge it ... whether you use it simply with marking points or lines, the graph is spread across the XY-axis.

Instead of writing Function = multiply by 3 we can use algebra. Graphically, \(f(x) = x^2\) is the same as the graph of \(y = x^2\). Writing graphs as functions in the form of \(f(x)\) is useful ...

Bar graphs are graphical representations of statistical data in the form of strips or bars. This allows viewers to understand the difference between the various parameters of the data at a glance ...
