Consider the linear map defined on with values in given by the matrix:
( 1 3 1 -2 )
( 3 9 4 -4 ) yes, this is supposed to be a matrix, i'm new
(-1 -3 -2 0 )
a) find all x e satisfying the linear equation Ax=b, with
b) find a basis for ker A
c) Using the Rank Theorem, find the dimension of im A
This is a past paper without solutions and would really help me revise, thank you very much !
