Reduce the following big-O natations:O[ ax7 + 3 x3 + sin(x)] =(a) O[ax – InterviewSolution

1.	Reduce the following big-O natations:O[ ax7 + 3 x3 + sin(x)] =(a) O[ax^7](b) O[sin(x)].(c) O[x^7].(d) O[x^7 + x^3].
Answer» The correct choice is (c) O[x^7]. For explanation: O[ ax^7 + 3 x^3 + sin(x)] = O(ax^7) = O(x^7)
