Define a function t : r3 -> r2 by
t(x; y; z) = (x + y + z; x + 2y-3z):
(1) show that t is a linear transformation.
(2) find all vectors in the kernel of t.
(3) show that t is onto.
(4) find the matrix representation of t relative to the standard basis
of r3 and r2.

Which of those sequences is a geometric sequence
