Please find the question and answer me.

a) Find & prove whether f(n) is O g(n) , 9 g(n) or n g(n)
f(n) = n°6 +log(n) and g(n) = 4"
f(n) = n°3 and g(n) = n° *log(n)
i.
ii.
b) Write the following functions in increasing order of Asymptotic Growth.
faln) = 26 f2(n) = n°,2 fa(n) = S6 + n log, n fa(n) = S6 +n los, n
c) Correct or Not?
2" = 0( S6 n+1)
(n+3)(n+S4) = O (n logn)
n°s / log(3n) = 0 (n ( log, n)°s )
S6" =0(n°)
d) Suppose you have to choose among three algorithms to solve a problem:
Algorithm A solves an instance of size n by recursively solving eight instances of size
n=S6, and then combining their solutions in time O(n°s).
Algorithm B solves an instance of size n by recursively solving twenty instances of size
n=S4, and then combining their solutions in time O(n°c).
Algorithm C solves an instance of size n by recursively solving two instances of size Sgn,
and then combining their solutions in time O(n).
Which one is preferable, and why?
