This image appears to contain a set of mathematical tasks. Here's a breakdown of the questions:

1. Solve the matrix equation with the unknown matrix X:

   2 & -1 \\ 0 & 3 \end{pmatrix} \times X = \begin{pmatrix} -1 & 4 \\ 0 & -3 \end{pmatrix}$$

2. Plot the graph of the function: $y = \sin(x) + 1 \quad \text{for} \quad x \in \left[ -\frac{\pi}{2}, \frac{\pi}{2} \right]$

3. Plot the function: $y = 2x + \frac{8}{x} + 2$

4. Write parametric equations of the line given by the intersection of two planes: $3x - 2y + z - 2 = 0 \quad \text{and} \quad 4x + y - 3z - 2 = 0$

5. Find the equation of the curve: $y^2 - 10x - 2y - 19 = 0$
