This image contains a math exercise in Arabic focused on analysis of functions, specifically examining properties like limits, derivatives, critical points, and behavior of the function across specific intervals and points. The graph provided represents a function $f(x)$ with various labeled tangents, points of interest, and some questions related to the function's properties at these points.

Here's a breakdown of the tasks and questions in the exercise:

1. Observing Derivatives: Questions involve finding values of the first and second derivatives at specific points, and making observations about the nature of these values (positive, negative, etc.).

2. Behavior and Interpretation of Tangents: Identify characteristics of tangents at points $T_1$, $T_2$, $T_3$, and $T_4$, and their implications on the shape and concavity of the function at these points.

3. Limits: Calculations for limits as $x$ approaches specific values (e.g., approaching positive or negative infinity, or near points with discontinuities).

4. Nature of Zeros and Extrema: Determine the behavior of the function in terms of the sign of $f(x)$, zeroes, and intervals of increase or decrease.

5. Solving Equations Involving Derivatives: Questions involve solving equations involving derivatives or setting up inequalities based on the sign of $f(x)$ and $f'(x)$.

Would you like a detailed solution for each part, or assistance with a specific section? Here are five questions to further your understanding:

1. What do positive and negative values of the first derivative tell you about a function?
2. How does the second derivative help us understand the concavity of a function?
3. Why are limits important when examining behavior near asymptotes or discontinuities?
4. What does the tangent line at a point signify in terms of slope and direction?
5. How can you determine intervals of increase and decrease for a function?

Tip: For any function, analyzing the first and second derivatives provides insights into its shape, turning points, and concavity.
