# Linear Algebra Problems

I have two questions that I need help with.

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 is in the attachment.

2) Are the following 3 vectors linearly dependent? (see attachment for the three vectors) How can you decide?

I hope you can help me. Thanks.

#### Solution Preview

Linear Algebra questions are indeed tricky. I have attached the solutions (see attachment) (also below, but see the attached file has the best formatting). I hope this helps in your understanding of these types of linear algebraic problems.

RESPONSE:

Problem 1:

The kernel is the vector subspace that maps into the zero vector. It

represents the number of dimensions lost in the transformation. So:

Dimension of range = dimension of domain - dimension of kernel

The rank ...

#### Solution Summary

This response provides the solutions for the two linear algebra problems.
