Transcribed Image Text:### Problem Set on Linear Algebra
**(c) Find a basis for the row space of A.**
There is a matrix on the left side, represented with open brackets indicating the rows of the matrix. An arrow points right, indicating the basis for the row space is to be determined.
**(d) Find a basis for the column space of A.**
The image depicts a matrix with open brackets indicating the columns of the matrix. Arrows indicate that the basis for the column space is to be determined.
**(e) Determine whether or not the rows of A are linearly independent.**
- Independent
- Dependent
A selection is to be made based on the linear dependence or independence of the rows.
**(f) Let the columns of A be denoted by \(a_1, a_2, a_3, a_4,\) and \(a_5\). Which of the following sets is (are) linearly independent? (Select all that apply.)**
Options are provided with checkboxes:
- \(\{a_1, a_2, a_4\}\)
- \(\{a_1, a_2, a_3\}\)
- \(\{a_1, a_3, a_5\}\)
In this problem, the user is expected to analyze the linear independence of the given sets of columns and select the appropriate options.
