## What is the difference between differentiable and continuous?

The difference between the continuous and differentiable function is that the continuous function is a function, in which the curve obtained is a single unbroken curve. It means that the curve is not discontinuous. Whereas, the function is said to be differentiable if the function has a derivative.

**How do you check a function is differentiable or not?**

If a graph has a sharp corner at a point, then the function is not differentiable at that point. If a graph has a break at a point, then the function is not differentiable at that point. If a graph has a vertical tangent line at a point, then the function is not differentiable at that point.

**Can a function be differentiable but continuous?**

No, this is not possible. However, you can have a function that is continuous but not differentiable (Weierstrass Function). There are infinitely many functions that are continuous but non differentiable.

### What is the relationship between differentiability and continuity?

Differentiability Implies Continuity If is a differentiable function at , then is continuous at . Now we see that , and so is continuous at . This theorem is often written as its contrapositive: If is not continuous at , then is not differentiable at .

**What is the difference between differentiability and differentiation?**

Differentiability refers to the existence of a derivative while differentiation is the process of taking the derivative. So we can say that differentiation of any function can only be done if it is differentiable.

**What makes a function continuous?**

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. Discontinuities may be classified as removable, jump, or infinite.

#### Which function is continuous?

In other words, a function is continuous if its graph has no holes or breaks in it. For many functions it’s easy to determine where it won’t be continuous. Functions won’t be continuous where we have things like division by zero or logarithms of zero.

**When a function is continuous is it differentiable?**

As long as a derivate can be found of a function at a certain point, the function is continuous at that point due to the proof aforementioned. If a Function is Continuous, is it Differentiable? A continuous function can be non-differentiable. Any differentiable function is always continuous.

**Is the function f differentiable at x = 0?**

So f is not differentiable at x = 0. If a function is continuous at a point, then it is not necessary that the function is differentiable at that point. What can you say about the differentiability of this function at other points?

## What is the difference between differentiability and continuity in calculus?

The difference between differentiability and continuity is based on what occurs in the function’s interval domain. A function is differentiable if there is a derivate at a certain point in the domain. A function is continuous if there are no breaks throughout the entire domain.

**How to prove that a function is continuous at x0?**

The above argument can be condensed and encapsuled to state: Discontinuity implies non-differentiability. If f is differentiable at a point x = x0, then f is continuous at x0. Let f(x) be a differentiable function on an interval (a, b) containing the point x0.
