Find the least integer n such that f(x) is o(xn) for each of these functions. a) f(x) = 2x2 + x3 log x b) f(x) = 3x5 + (log x) 4 c) f(x) = (x4 + x2 + 1)∕(x4 + 1) d) f(x) = (x3 + 5 log x)∕(x4 + 1) 9. show that x2 + 4x + 17 is o(x3) but

Axel follows these steps to divide 40 by 9: start with 40. 1. divide by 9 and write down the remainder. 2. write a zero after the remainder. 3. repeat steps 1 and 2 until you have a remainder of zero. examine his work, and then complete the statements below.
