2.1 (d) parts (a) and (b)
threshold: pts
4.0 pts
A + B identified as O(m*n) with reasoning as to the number of operations required to add the elements in two mxn matrices; Ax identified as O(n^2) with reasoning that counts the number of operations at each row.
3.0 pts
Correctly identified O(m*n) and O(n^2), with small logical errors in reasoning.
2.0 pts
Either correctly identified both O(m*n) and O(n^2) without any reasoning explained or incorrectly identified one of them, but with some explanation provided for both.
1.0 pts
Incorrectly identified both but an effort was made to explain the thought process
