Let's follow the calculations from the previous page in Geogebra. [br][br]To calculate f first then g of 1, type [code]f(1)[/code] to create a number (Geogebra should call it "[code]a[/code]"), then type [code]g(a)[/code] to run [code]g[/code] on the output of [code]f[/code].

Now try [code]g[/code] first then [code]f[/code] by typing [code]g(1)[/code] to create a number (probably "[code]c[/code]"), then run [code]f[/code] on that by typing [code]f(c)[/code].[br][br]Great! As expected, the two different compositions return two different numbers. We'll see function composition quite a bit later. It might look more complicated, but at it's core it is never more complicated than it was in this example.[br][br]Move on to the next activity for a brief end of chapter quiz on functions.
