    Linear Transformation

    This problem is due tomorrow, i need help.

    Letting T: R^4 -> R^3, where T(v)=Av.

    Matrix A: 2, 1, -1, 1
    1, 2, 0, 5
    4, -1, -1, 0

    note: this is a 3x4 matrix.
    Find: Kernel(T), Nullity(T), Range(T), Rank of T, Rank of matrix A.

    Some things I know about this problem:
    Ker(T) = Null(A).
    The 3rd row of the matrix has to all be zeros.

    The problem I am having most is, reducing matrix A into its reduced form or whatever it's called.

    Please help..
