Program Code – The Trio of Mathematical Analysis: Range, Domain, and Function

# Import necessary libraries
import numpy as np

# Define a function to compute the range of a given list of numbers
def compute_range(numbers):
    This function computes the range of a given list of numbers.
    numbers (list): A list of numerical values.
    float: The range of the given numbers.
    return max(numbers) - min(numbers)

# Define a function to determine the domain of a function given its formula as a lambda function and its input range
def determine_domain(function, input_range):
    This function determines the domain of a function given its formula and its input range.
    function (function): A lambda function representing the formula of the function.
    input_range (list): A list representing the input range of values to test.
    list: A list of values that represent the domain of the function.
    domain = []
    for x in input_range:
    return domain

# Define a function that represents a mathematical function, for instance, f(x) = x^2
f = lambda x: x**2

# Example input range of values for testing
input_range = np.arange(-10, 11, 1)  # Generates numbers from -10 to 10

# Compute the range of the input range of values
range_of_values = compute_range(input_range)

# Determine the domain of the function 'f' given the input range
domain_of_f = determine_domain(f, input_range)

print(f'Range of input values: {range_of_values}')
print(f'Domain of the function: {domain_of_f}')

Code Output:

Range of input values: 20
Domain of the function: [-10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Code Explanation:

This meticulously crafted program tackles the trio of mathematical analysis: range, domain, and function, with unparalleled elegance.

  • Function 1 – compute_range(numbers): A straightforward but essential function, it takes a list of numbers and computes the range, which is the difference between the highest and the lowest number in the list. This is achieved by utilizing Python’s built-in max() and min() functions.
  • Function 2 – determine_domain(function, input_range): The heart of our mathematical analysis. This function determines the domain of a given function. It accepts two parameters: a function (expressed as a lambda function) and a list of input values (input_range). It then attempts to apply the function to each value in the input_range. If the function execution is successful (i.e., does not raise an exception), the value is considered part of the function’s domain and is added to a list. The domain, a collection of all such values, is then returned.
  • Defining a Mathematical Function (f): For demonstration purposes, a simple lambda function f = lambda x: x**2 is defined, representing (f(x) = x^2).
  • Example Input Range: An input range of values from -10 to 10 is generated using NumPy’s arange function. This range is both used to compute the range of input values and to determine the domain of our lambda function f.
  • Computing the Range and Domain: Finally, the program computes the range of the input values using compute_range and determines the domain of the function f using determine_domain, illustrating the input’s range and the function’s domain vividly.

Crafted with a blend of functionality and streamline code architecture, this program not only achieves its objectives but does so in a manner that is accessible for further exploration and analysis in the fascinating world of mathematical analysis. Thanks a bunch for sticking around till the end! Keep crunching those numbers. 😄
