Exponential Growth vs. Linear Growth

"Linear functions grow by [color=#9900ff][b]equal differences[/b][/color] over equal intervals. [br]Exponential functions grow by [color=#9900ff][b]equal factors[/b][/color] over equal intervals."[br][br]Source: [url=http://www.corestandards.org/Math/Content/HSF/LE/]http://www.corestandards.org/Math/Content/HSF/LE/[/url][br][br][color=#cc0000][b]Check it out![/b][/color][br]Note the growth of the exponential function when its base is 2 and compare this growth to the exponential function with base of 3. (When you make the base = 3, you may want to zoom out before sliding the slider.) [br][br]

Fastest Growing Function?

The applet below contains a collection of 6 functions.[br]Each function is color-coded so its graph is the same color as its description & equation listed on the right. [br][br][i]Of all these listed functions, which one will eventually "beat all the others", so to speak, with respect to increasing at the fastest rate? Explain your reasoning. [/i]
