Find the least integer n suchthat f (x ) is 0 (x ) for the given functions.
Make sure to show your work and include the smallest corresponding witnesses
C and k
(a) f (x ) = 5x 4 + 4x + 1
Give a big-O estimate for the function below.
For the function g in your estimate, f (x ) is 0 (g (x )), use a simple function
8 of smallest order.
Determine whether the function, f (x ) = 2* + 2 is of order 2
(i.e. determine if f (x ) 0(2 >>.
Show your work by determining if f (x ) is 0 (2 ) and ).
