Let
A=[[1,-2,-1],[-4,4,0],[4,0,4]]and
b=[[b_(1)],[b_(2)],[b_(3)]]. Show that the equation
Ax=bdoes not have a solution for all possible
b, and describe the sel of all
bfor which Ax
=bdoes have
asolution. How can
&be shown that the equation
Ax=bdoes not have a solution for all possible
b? Chsose the correct answer below B. Row reduce the matric A to demonstrate that
Ahas a pivot position in every row. C. Rowe reduce the matrix A to demsnstrate that A does not hame a pivet position in every row. D. Find a vector
xfor which
Ax=bis the zero vector E. Find a vector
bfor which the solution to
Ax=bis the zero vector
