Asymptotic Bounds

• Let f(x) and g(x) be mathematical functions.

• Definition. Function f is asymptotically bounded by g if, for some N � 0 and k � 0, the inequality

  
  
  k * | g(x) | � | f(x) |
  

holds for all x � N.

• If f is asymptotically bounded by g, we write:

  
  

f = O(g)

read "f is big Oh of g".
