Composition of Functions Part 4

Let's follow the calculations from the previous page in Geogebra. To calculate f first then g of 1, type f(1) to create a number (Geogebra should call it "a"), then type g(a) to run g on the output of f.
Now try g first then f by typing g(1) to create a number (probably "c"), then run f on that by typing f(c). 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. Move on to the next activity for a brief end of chapter quiz on functions.
