(a) Find a growth rate that squares the run time when we double the input size. That is, if T(n) = X, then T(2n) = x2


(b) Find a growth rate that cubes the run time when we double the input size. That is, if T(n) = X, then T(2n) = x3


Using the definitions of big-Oh and Ω, find the upper and lower bounds for the following expressions. Be sure to state appropriate values for c and n0.


(a) c1n


(b) c2n3
+ c3


(c) c4n log n + c5n


(d) c62n
+ c7n6

a) T(n) = e^n
if n' = 2n,
then T(n') = e^n' = e^2n = (e^n)^2 = ( T(n) )^2
Proves that:
T(n) = e^n squares if the input size(n) is doubled
b) T(n) = e^(3n/2)
if n' = 2n,
then T(n') = e^(3n'/2) = e^(3n) = (e^(3n/2))^3 = ( T(n) )^3
Proves that:
T(n) = e^(3n/2) cubes if the input size(n) is doubled
Using the definitions of big-Oh and Ω,...
