# Solved: function continuity python

The main problem related to function continuity in Python is that functions are not always continuous. A function is said to be continuous if its graph is a single, unbroken curve without any gaps or jumps. In Python, functions can have discontinuities due to certain conditions such as division by zero, taking the square root of a negative number, and taking the logarithm of a negative number. These discontinuities can lead to unexpected results and errors in your code if not handled properly.

```
def continuity(f, x, h):
return (f(x + h) - f(x)) / h

# Driver Code
def f(x):
return x * x * x + 2 * x - 5

x = 3.0; h = 0.0001; print("Value of derivative is", continuity(f, x, h))```

# Line 1: This line defines a function called continuity that takes three parameters: f, x, and h.
# Line 2: This line is the driver code that defines a function f(x) which returns the value of x cubed plus two times x minus five.
# Line 3: This line sets the values of x and h to 3.0 and 0.0001 respectively.
# Line 4: This line prints out the value of the derivative calculated using the continuity function with f, x, and h as parameters.

## Continuous function in Python

A continuous function is a mathematical function that can be evaluated at any point on its domain. In Python, continuous functions are defined using the lambda keyword. Lambda functions allow for the creation of anonymous functions, which are functions that do not have a name and can be passed as arguments to other functions. Continuous functions can be used to perform calculations on data sets or to define complex mathematical operations. They are also commonly used in machine learning algorithms for tasks such as regression and classification.

## How do you check if a function is continuous

In Python, you can check if a function is continuous by using the scipy.integrate.quad() function. This function takes in two parameters: the first is a callable function that represents the integrand, and the second is a tuple of two numbers that represent the lower and upper limits of integration. The quad() function will then return a tuple containing an estimate of the integral and an estimate of its absolute error. If this value is close to zero, then it indicates that the integral was successfully calculated and thus, that the given function is continuous over its given domain.
