    Basis of Image & Kernal

    I have attached the question.

    To calulate U_1 , I put L_1 in a matrix form as follows

    1 1 2 -1
    2 4 1 -1

    and made that equal to the zero vector

    0
    0

    I row reduced it with leading ones,
    however I don't know what to do from there - and I certainly am not sure how the calculate the Image of L_2 either nor the others.

    Hints and advice will be very much appreciated, thank you.
