** Please see the attachment for complete questions (1 and 2) **
1. Find the Boolean Product of matrices A and B.
2. Given matrix A, compute:
(a) A^-1 (A-inverse)
3. Solve the following systems of equations.
x1 + x2 = 0
-x1 + x2 + x3 = -1
-1x2 + x3 = 2
4. (a) Define the function f: R --> R by f(x) = x^3 + 4.
Briefly explain why f is a 1-1 (one-to-one) function. No proof necessary, just an explanation in some detail.
(b) Is the function g: R --> Z defined by g(n) = ceiling(n/2) a one to one function? Explain.
(c) Briefly explain what f^-1 means in general and then find f^-1 for the function f in part a.
5. Expand (A + B)(A - B). Use the procedures of basic matrix laws.© BrainMass Inc. brainmass.com December 24, 2021, 9:45 pm ad1c9bdddf
