Introduction

In mathematics, the range of a function is the set of all possible output values it can produce for the given input values. When dealing with square root functions, it's essential to understand how to find the range, as it can be a bit tricky. In this article, we'll explore how to find the range of a square root function and apply it to a specific problem.

What is the Range of a Square Root Function?

The range of a square root function is the set of all possible output values it can produce for the given input values. In other words, it's the set of all possible values that the function can take on. For a square root function, the range is always non-negative, as the square root of a negative number is undefined in the real number system.

Finding the Range of a Square Root Function

To find the range of a square root function, we need to consider the following:

The domain of the function: The domain of a square root function is the set of all possible input values. For a square root function, the domain is always non-negative.
The behavior of the function: The behavior of a square root function is such that it increases as the input value increases.

Applying the Concept to a Specific Problem

Now, let's apply the concept to a specific problem. We are given the following information:

The range is $\$243$ .
$s^2 = 11,983$ dollars $^2$ (Round to the nearest whole number as needed.)
$s = \$\square$ (Round to two decimal places as needed.)

Step 1: Find the Square Root of 11,983

To find the range of the function, we need to find the square root of 11,983. We can use a calculator or a mathematical software to find the square root.

import math
s_squared = 11983
s = math.sqrt(s_squared)
s = round(s, 2)
print(s)

Step 2: Find the Range of the Function

Now that we have found the square root of 11,983, we can find the range of the function. The range of a square root function is always non-negative, as the square root of a negative number is undefined in the real number system.

# Define the variable
range_of_function = s
print("The range of the function is: $", range_of_function)

Conclusion

In conclusion, the range of a square root function is the set of all possible output values it can produce for the given input values. To find the range of a square root function, we need to consider the domain of the function and the behavior of the function. We can apply this concept to a specific problem by finding the square root of the given value and rounding it to two decimal places.

Final Answer

The final answer is $\boxed{\$109.99}$ .
