Given a function f(n) that describes the amount of resources (CPU time, RAM, disk space, etc) consumed by an algorithm when applied to an input of size of n, we define up to three asymptotic notations for describing its performance for large n. An asymptote (or asymptotic function) is simply some other function (or relation) g(n) that f(n) gets increasingly close to as n grows larger and larger, but never quite reaches. You can eliminate the "+7" on the right and pick c 1 = 1.
