Short Answer

Find the image and kernel of the transformation TinT(x0,x1,x2,x3,...)=(0,x0,x2,x4) from Vto V.

The solution is the image consist of all infinite sequence with the initial element as 0 and the kernel contains zero sequence only.

See the step by step solution

Step by Step Solution

Step1: Explanation of the solution

Consider the sequence as follows.

T(x0,x1,x2,x3,...)=Tx0,x2,x4

The image of the sequence is as follows.

0,x0,x2,x4,...

Therefore, the image consist of all infinite sequence whose initial element is 0.

Step2: Find kernel of the sequence

Consider the sequence as follows.

T(x0,x1,x2,x3,...)=Tx0,x2,x4

Now, kernel of the sequence as follows.

T0,x0,x1,x2,0,x2,0,x3,0,...=0,0,0,0,...x0=x1=x2=...=0

Thus, the kernel contains zero sequence only.

Hence, the image consist of all the infinite sequence with initial element as 0 whereas the kernel contains zero sequence only.
