Show that if f(n) is O(g(n)) and d(n) is O(h(n)) then f(n) + d(n) is O(g(n) + h(n)).
GaryK [48]
f(n)\in\mathcal O(g(n)) is to say

|f(n)|\le M_1|g(n)|

for all n beyond some fixed n_1.

Similarly, d(n)\in\mathcal O(h(n)) is to say

|d(n)|\le M_2|h(n)|

for all n\ge n_2.

From this we can gather that

|f(n)+d(n)|\le|f(n)|+|d(n)|\le M_1|g(n)|+M_2|h(n)|\le M(|g(n)|+|h(n)|)

where M is the larger of the two values M_1 and M_2, or M=\max\{M_1,M_2\}. Then the last term is bounded above by

M(|g(n)|+|h(n)|)\le2M\max\{|g(n)|,|h(n)|\}

from which it follows that

f(n)+d(n)\in\mathcal O(\max\{g(n),h(n)\})
