Algorithmic Analysis I want a solution with explanation

2. For each of the following functions, indicate how much the function's value will change it its argument is increased Triple. (a) 3n3 (b) log2n2 (c) 3n d) n3 ALGORITHM JAZAN(A[0..m - 1, 0..m] ) //Input: An m(m+1) matrix A[0..m - 1, 0.m] of real numbers for i0 to m2 do for ji+1 to m1 do for ki to m do A[j,k]A[j,k]A[i,k]A[j,i]/A[i,i] a) What does this algorithm compute? b) What is its basic operation? c) How many times is the basic operation executed? d) What is the efficiency class of this algorithm
