Expert Solution
Step 1: We give definition of linear transformation.

(.)  Linear transformation: 

Let U and V be two vector spaces over a same field  F, then function  T space colon space U rightwards arrow space V   is called a  linear transformation if,

left parenthesis i right parenthesis space space space T open parentheses space u subscript 1 plus u subscript 2 close parentheses space equals space T open parentheses u subscript 1 close parentheses plus T open parentheses u subscript 2 close parentheses space space space space f o r space a l l space u subscript 1 comma u subscript 2 element of U
left parenthesis i i right parenthesis space space space space T left parenthesis a u right parenthesis space equals space a T left parenthesis u right parenthesis space space space f o r space a l l space a element of F space comma space u element of U

Now we find which of the following given are linear transformations.
