What Is The Range Of The Function $y = \sqrt{x+5}$?A. $y \geq -5$ B. $y \geq 0$ C. $y \geq \sqrt{5}$ D. $y \geq 5$
Introduction
When dealing with functions, understanding the range is crucial in determining the possible output values. In this case, we are given the function , and we need to find its range. The range of a function is the set of all possible output values it can produce for the given input values. In other words, it is the set of all possible y-values that the function can take.
Understanding the Function
The given function is . This is a square root function, which means that the output value (y) is the square root of the input value (x+5). The square root function is defined only for non-negative values, which means that the input value (x+5) must be greater than or equal to 0.
Finding the Range
To find the range of the function, we need to determine the possible output values (y-values) that the function can produce. Since the input value (x+5) must be greater than or equal to 0, we can set up the inequality . Solving this inequality, we get .
Analyzing the Square Root Function
Now that we have the inequality , we can analyze the square root function. The square root function is defined only for non-negative values, which means that the output value (y) must be greater than or equal to 0. Therefore, we can set up the inequality .
Combining the Inequalities
We have two inequalities: and . These inequalities represent the possible input values (x-values) and output values (y-values) of the function. Since the function is defined only for non-negative values, the output value (y) must be greater than or equal to 0.
Conclusion
Based on the analysis, we can conclude that the range of the function is . This means that the function can produce any output value greater than or equal to 0.
Comparison with Options
Let's compare our conclusion with the given options:
A. B. C. D.
Our conclusion matches option B, which states that . Therefore, the correct answer is option B.
Final Answer
The final answer is option B, which states that the range of the function is .
Introduction
In our previous article, we discussed the range of the function . We concluded that the range of the function is . In this article, we will provide a Q&A section to help clarify any doubts and provide additional information.
Q&A
Q1: What is the range of the function ?
A1: The range of the function is . This means that the function can produce any output value greater than or equal to 0.
Q2: Why is the range of the function ?
A2: The range of the function is because the square root function is defined only for non-negative values. Since the input value (x+5) must be greater than or equal to 0, the output value (y) must also be greater than or equal to 0.
Q3: What is the minimum value of the function ?
A3: The minimum value of the function is 0. This is because the function can produce any output value greater than or equal to 0.
Q4: Can the function produce negative values?
A4: No, the function cannot produce negative values. This is because the square root function is defined only for non-negative values.
Q5: What is the maximum value of the function ?
A5: The maximum value of the function is not defined. This is because the function can produce any output value greater than or equal to 0, and there is no upper bound.
Q6: How does the function compare to the function ?
A6: The function is different from the function . The function is defined only for non-negative values, while the function is defined for all real values.
Q7: Can the function be used to model real-world phenomena?
A7: Yes, the function can be used to model real-world phenomena. For example, it can be used to model the growth of a population or the spread of a disease.
Q8: How does the function relate to the concept of domain and range?
A8: The function is related to the concept of domain and range. The domain of the function is all real values greater than or equal to -5, and the range of the function is all real values greater than or equal to 0.
Conclusion
In this Q&A article, we provided answers to common questions about the range of the function . We hope that this article has helped to clarify any doubts and provide additional information.
Final Answer
The final answer is that the range of the function is .
