A function created by applying functions one after another in sequence
Order matters - changes order = different result
ggg is applied first, then fff
Right to left - closest to xxx applied first
Usually give completely different results
f(f(x))f(f(x))f(f(x)) - apply fff twice
(x+2)2(x+2)^2(x+2)2
x2+2x^2+2x2+2
Apply hhh first, then ggg, then fff
f(x)+g(x)f(x) + g(x)f(x)+g(x)
f(x)imesg(x)f(x) imes g(x)f(x)imesg(x)
f(x)divg(x)f(x) div g(x)f(x)divg(x) or rac{f(x)}{g(x)}
Getting order wrong - remember ggg first, then fff
Avoid errors: (2x−3)2(2x-3)^2(2x−3)2 not 2x−322x-3^22x−32
[f(x)]2[f(x)]^2[f(x)]2 - it means f(f(x))f(f(x))f(f(x)), not squaring
