The image contains handwritten mathematical problems in Arabic. Here's a brief outline of the questions and how to approach solving them:
Problem 1:
The first part introduces a function and asks to:
- Study the sign of the function — meaning to analyze where is positive, negative, or zero.
- Construct a variation table for .
- Calculate .
- Determine the function's domain and behavior for specific intervals.
Solution for Problem 1:
To address this:
- Domain: Since it's a polynomial, the domain is .
- Sign study: Solve to find critical points. Factor or apply methods to solve higher-degree polynomials.
- Variation table: Derive to find the intervals of increase or decrease.
- : Direct substitution gives .
Problem 2:
The second problem asks for the function .
- Study the function's sign and variation.
- Determine points of interest and its behavior near zero and infinity.
Solution for Problem 2:
- Domain: The square root function restricts the domain to , excluding due to division by zero.
- Sign study: Analyze the function’s behavior by solving .
- Asymptotes: Analyze the limits as and .
There are additional steps in the image, like forming tables and studying other properties.
