document.write( "In traditional calculus, a function is defined as a relation between two terms called variables because their values vary. Call the terms, for example, x and y. If every value of x is associated with exactly one value of y, then y is said to be a function of x. It is customary to use x for what is called the \"independent variable,\" and y for what is called the \"dependent variable\" because its value depends on the value of x.[1] Therefore, y = x2 means that y, the dependent variable, is the square of x, the independent variable.[1][2]\r<BR>\n" );
document.write( "\n" );
document.write( "The most common way to denote a \"function\" is to replace y, the dependent variable, by f(x), where f is the first letter of the word \"function.\" Thus, y = f(x) = x2 means that y, a dependent variable, a function of x, is the square of x. Also, in this form, the expression is called an \"explicit\" function of x, contrasted with x2 &#8722; y = 0, which is called an \"implicit\" function.[1]<BR>\n" );
