Question:
Linear Algebra Problems
1) How would you find a basis of the kernel, a basis of the image and determine the dimension of each for this matrix? The matrix given below.
      1  2  1  2  1
      1  2  2  1  2
      2  4  3  3  3
      0  0  1 -1 -1
2) Are the following 3 vectors linearly dependent? (see attachment for the three vectors) How can you decide?
      1     1      1
      1     2      4
      1     3      7
      1      4     10
