Square Root of 5-x
The expression "square root of 5-x" represents a mathematical function involving the square root of the quantity (5 - x). Here's a breakdown of the key points:
- Domain: The expression is defined for values of x where 5 - x ≥ 0, which simplifies to x ≤ 5.
- Range: The range of the function includes all non-negative real numbers, meaning the result of the square root operation is always greater than or equal to zero.
- Behavior: As x approaches 5 from the left (x → 5⁻), the square root function approaches 0. For x values less than 5, the value of the function increases.
- Graph: The graph of y = √(5 - x) is a decreasing curve that starts at (0, √5) and approaches the x-axis as x increases.
Understanding the properties and behavior of the "square root of 5-x" function is essential in various mathematical contexts, including algebra and calculus.

Introduction to Square Root of 5-x
The "square root of 5-x" refers to a mathematical expression involving the square root of the quantity (5 - x). This function is fundamental in algebra and calculus, offering insights into how values of x affect the outcome of the square root operation. Understanding its domain, range, and graphical representation provides a deeper understanding of its applications in mathematical modeling and problem-solving.
Domain and Range of the Function
The "square root of 5-x" function has specific constraints on its domain and range:
- Domain: Defined for values of x where 5 - x ≥ 0, which simplifies to x ≤ 5. Therefore, the function is defined for x ranging from negative infinity to 5, inclusive.
- Range: The range of the function includes all non-negative real numbers. This is because the square root function outputs non-negative values, meaning the result is always greater than or equal to zero.
Behavior of the Function
The behavior of the "square root of 5-x" function varies depending on the value of x:
- As x increases from negative infinity towards 5, the value inside the square root, 5 - x, decreases.
- For x ≤ 5, the function outputs real values since the square root of a non-negative number is defined and real.
- As x approaches 5 from the left (x → 5⁻), the function approaches 0.
- The function is decreasing because as x increases, the value of 5 - x decreases, resulting in a smaller square root value.
Graphical Representation
The graphical representation of the "square root of 5-x" function reveals its visual characteristics:
- The graph is defined for x values where 5 - x ≥ 0, hence x ≤ 5.
- It starts at the point (0, √5) and decreases as x increases towards 5.
- As x approaches 5 from the left, the graph approaches the x-axis at (5, 0).
- Overall, the graph is a decreasing curve that illustrates how the function behaves visually as x varies.
