JavaScript Functions

Background

Carefully study the examples on the resources page: A function to convert from celsius to fahrenheit, Calling a function to change colors in a page, Calling a function with parameters.

Task 1: computing an average (8 points)

Write a web page that prompts the user for two numbers and prints their average. You must write the computation of average as a function average that takes two numbers and returns their average.

Task 2: Changing the background of a page (10 points).

Write a function that takes a color and changes the background of the entire page to that color. Note that in our examples the <body> tag has an id thepage.

Add two buttons to the page (each in its own form): one to set the page background to any color, the other one to restore it back to white. Both buuttons should call the same function, just with different colors.
