## Program Code – Navigating the Concepts of Range and Domain in Math

```
``````
def calculate_range(numbers):
'''Calculate the range of a list of numbers.'''
# Ensure the input is not empty
if not numbers:
return None
# Calculate the range
return max(numbers) - min(numbers)
def calculate_domain(function, values):
'''Calculate the domain of a given function for a list of values.'''
domain = []
for x in values:
try:
# Try executing the function with x
y = function(x)
domain.append((x, y))
except Exception as e:
# If an error occurs, ignore this value of x
print(f'Skipping value {x}: {e}')
return domain
# Example function that might not work for all values
def example_function(x):
if x == 0:
raise ValueError('x cannot be 0')
return 10 / x
# Calculate the range of a list of numbers
numbers_range = calculate_range([1, 2, 3, 4, 5, 6, 7, 8, 9])
print(f'Range: {numbers_range}')
# Calculate the domain of the example_function over a range of values
domain_results = calculate_domain(example_function, range(-5, 6))
print('Domain:')
for x, y in domain_results:
print(f'f({x}) = {y}')
```

### Code Output:

```
Range: 8
Skipping value 0: x cannot be 0
Domain:
f(-5) = -2.0
f(-4) = -2.5
f(-3) = -3.3333333333333335
f(-2) = -5.0
f(-1) = -10.0
f(1) = 10.0
f(2) = 5.0
f(3) = 3.3333333333333335
f(4) = 2.5
f(5) = 2.0
```

### Code Explanation:

The program is composed out of two main functions, `calculate_range`

and `calculate_domain`

, designed to help understand the concepts of range and domain in mathematics through computation.

`calculate_range(numbers)`

: This function calculates the range of a list of numbers. It takes a list of numbers as input, checks if the list is not empty, then finds the maximum and minimum values in the list. The range is calculated by subtracting the minimum value from the maximum value. If the list is empty, it returns`None`

.`calculate_domain(function, values)`

: This function calculates the domain of a given mathematical function over a list of x-values. It iteratively applies the function to each x-value in the provided list,`values`

. If the function executes successfully, the (x, y) pair is added to the domain list. If an error occurs (e.g., division by zero), the error is caught, and the function skips over that x-value, ensuring the program doesn’t crash. This approach allows testing functions that are undefined for certain values of x, like the`example_function`

.

The `example_function(x)`

provided raises an exception when `x`

is 0, simulating a function that is not defined for all x-values.

Finally, the results are printed to the console, showing the range for a simple list of numbers, and demonstrating how the domain of `example_function`

is calculated, excluding the undefined point where `x`

is 0. This program effectively showcases how to compute and understand these fundamental mathematical concepts programmatically.
