FINDING A BASIS FOR THE KERNEL OR IMAGE. To find the kernel of a matrix A is the same as to solve the system AX = 0, and one usually does this by putting A in rref. The matrix A and its rref B have exactly the same kernel. In both cases, the kernel is the set of solutions of the corresponding homogeneous linear equations, AX = 0 or BX = 0.
The image is the set of all points in $\mathbb{R}^4$ that you get by multiplying this matrix to points in $\mathbb{R}^5$, you can find these by checking the matrix on the standard basis. The kernel is the set of all points in $\mathbb{R}^5$ such that, multiplying this matrix with them gives the zero vector. Again you can find this in a similar way.
4.1 The Image and Kernel of a Linear Transformation. Definition. The image of a function consists of all ... Then B is the identity matrix, so ker(B) = {0}.
matrix A, that is, T(x) = Ax. Then the matrix equation Ax = b becomes T(x) = b: Solving the equation means looking for a vector x in the inverse image T 1(b). It will exist if and only if b is in the image T(V). When the system of linear equations is homoge-neous, then b = 0. Then the solution set is the subspace of V we’ve called the kernel ...
The image of a linear transformation or matrix is the span of the vectors of the ... The dimensions of the image and the kernel of A are related in the Rank ...

nd the image of a matrix, reduce it to RREF, and the columns with leading 1’s correspond to the columns of the original matrix which span the image. We also know that there is a non-trivial kernel of the matrix. We know this because the the dimension of the
After a long night of studying I finally figured out the answer to these. The previous answers on transformation were all good, but I have the outlined ...
