Solved Let B 1 1 0 0 1 1 1 0 1 And B 1 Chegg Solution: since square a matrix is invertible if and only if elimination yields the same number of pivots as rows, we just need to do elimination on a and b and see what conditions on their entries ensure that we get a pivot in every row. Question: exercise 2.1.60 let a 1 0 2 2 1 5 1 1 suppose a row operation is applied to a and the result is b 1 2 2 2 1 4 5 14 (a) find the elementary matrix e such that ea = b. (b) find the inverse of e, e 1, such that e 'b=a.

Definition: a function is a rule by which we relate two sets a and b (say) in such a way that each element of a is assigned with one and only one element of b. for example is a function from a to b. its domain = {1,2,3} and range = {4,5} 1 4 2.
