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.
