The image presents two problems involving matrices.

**Problem 21:**

Matrix A is given as:

\[
A = \begin{bmatrix} 3 & 1 \\ 2 & 1 \end{bmatrix}
\]

**Problem 22:**

Matrix A is given as:

\[
A = \begin{bmatrix} 2 & 0 \\ 4 & 1 \end{bmatrix}
\]

No graphs or diagrams are present in the image. Each problem involves a 2x2 matrix, which is a rectangular array of numbers with two rows and two columns. The first matrix consists of the entries 3, 1 in the first row and 2, 1 in the second row. The second matrix consists of the entries 2, 0 in the first row and 4, 1 in the second row. These matrices can be used for various operations such as addition, multiplication, finding the determinant, or calculating the inverse, providing essential components in linear algebra studies.
