Big O notation as a function of "x", namely 6"x". Now one may apply the second rule: 6"x" is a product of 6 and "x" in which the first factor does not depend on "x". Omitting this factor results in the simplified form "x". Thus, we say that "f"("x") is a "big-oh" of ("x"). Mathematically, we can write "f"("x") = "O"("x"). One may confirm this calculation using the formal definition: let "f"("x") = 6"x" − 2"x" + 5 and "g"("x") = "x". Applying the formal definition from above, the statement that "f"("x") = "O"("x") is equivalent to its expansion, for some suitable choice
