Question

I need help with all of questions in the picture below.

Definitions: Let T be a transformation from a vector space Vinto a vector space W
The kernel of Tis the set {veV:T(v) = 0}
The range of Tis the set {T(v): veV}.
Tis one-to-one if, for all u and v in V, T(u) =T(v) implies u = v.
note: The kernel of T is a subspace of V and the range of T is a subspace of W.
