The following set of short questions will focus on getting you familiar with JavaScript functions. All functions and testing should appear in a single XHTML 1.0 Strict page.

All your JavaScript functions must be declared in the document head section and each functions name must be as specified below. To demonstrate the functionality of each method, you must make function calls in the document body. Include a heading (h1... h6) that indicates which function is being tested before each function demonstration. The use of Global Variables is forbidden!
