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.
