# What defines differentiability?

## What defines differentiability?

In calculus (a branch of mathematics), a differentiable function of one real variable is a function whose derivative exists at each point in its domain. More generally, for x0 as an interior point in the domain of a function f, then f is said to be differentiable at x0 if and only if the derivative f ′(x0) exists.

## Is a straight line differentiable?

If a function f is differentiable at its entire domain, that simply means that you can zoom into each point, and it will resemble a straight line at each one (though, obviously, it can resemble a different line at each point – the derivative need not be constant). (For all other x, of course, it is differentiable).

**What is continuity and change in history?**

Further, historical thinking skills help historians determine the cause and effect of particular historical events on present day.

## How do you show continuity of a function?

A function is said to be continuous on the interval [a,b] if it is continuous at each point in the interval. Note that this definition is also implicitly assuming that both f(a) and limx→af(x) lim x → a exist. If either of these do not exist the function will not be continuous at x=a .

**Why is continuity important in history?**

Although individuals only live a relatively short time, institutions, ideas, and problems can endure for long periods of time, even thousands of years. This is known as continuity. Although continuity is important in the study of history, historians also recognize that society is constantly undergoing change.

### Why is recognizing patterns of continuity and change over time important?

They can record the changes from key crisis events. They also can keep track of the major continuities in the time period. It also helps students identify in the time period at least three major events that demonstrate the major changes.

### How do you write a continuity and change thesis statement?

**What does it mean to think historically?**

**How do you determine differentiability?**

- Lesson 2.6: Differentiability: A function is differentiable at a point if it has a derivative there.
- Example 1:
- If f(x) is differentiable at x = a, then f(x) is also continuous at x = a.
- f(x) − f(a)
- (f(x) − f(a)) = lim.
- (x − a) · f(x) − f(a) x − a This is okay because x − a = 0 for limit at a.
- (x − a) lim.
- f(x) − f(a)

## What are the 3 conditions of continuity?

Key Concepts. For a function to be continuous at a point, it must be defined at that point, its limit must exist at the point, and the value of the function at that point must equal the value of the limit at that point.
