5.
Order Notation. Consider each pair of functions below. Give a formal proof
using a direct proof technique, that f(n) e O(g(n)). Recall that f(n) E O(g(n)) if and
only if 3c € R+, 3no E N, Vn E N, n > no→ f(n) < c· g(n)
f(n) = 7n² log, n+ 12n + 7 and g(n) = 3n³ – 4n? + 12.
a.
f(n) =
2n2 -n+6
n-15
and g(n) = n? – 16.
b.
