Let T : R2 → R3 be a linear transformation such that T( e⃗1 ) =
(2,3,-5) and T( e⃗2 ) = (-1,0,1).
Determine the standard matrix of T.
Calculate T( ⃗u ), the image of ⃗u=(4,2) under T.
Suppose T(v⃗)=(3,2,2) for a certain v⃗ in R2 .Calculate the
image of ⃗w=2⃗u−v⃗ .
4. Find a vector v⃗ inR2 that is mapped to ⃗0 in R3.
