Using the analogous definition for 2O(g(x)), show that f(x) 2 O(g(x)) ; f(x) O(2g(x) ).

Asymptotic notation is often used in expressions, e.g., "f(2) Er + 09:))" where r3 + (()) is defined to be: { x + h(r) h(1) E O (9(2))}. Asymptotic notation is often used in expressions, e.g., "f(2) Er + 09:))" where r3 + (()) is defined to be: { x + h(r) h(1) E O (9(2))}
