# How do you know if a function is differentiable

One of the most important skills that students need to learn is How do you know if a function is differentiable. ## Differentiable

The rules of differentiation tell us that the derivative of \(x^3\) is \(3x^2\), the derivative of \(x^2\) is \(2x\), and the derivative So, the derivative of \(f\) is \(f'(x) = 3x^2 + 6x + 2\). This derivative exists for every possible value of \(x\)! we can    ## Differentiable function

Presumably, you have been given a function defined piecewise over an interval, and you want to know whether the function is differentiable at the edges where the pieces meet. Suppose the

To ensure you are clarifying the math question correctly, re-read the question and make sure you understand what is being asked. If you are still unsure, ask a friend or teacher for help. If you're looking for help with arithmetic, there are plenty of online resources available to help you out. Clear up mathematic

Though i would say that it is umable to solve word problems. Thankyou so muchâ¤. Very useful app. I also love how you can see how the problem is worked out to see where you messed up. Love the app but please add that.

Ronald Jewell

This app is AMAZING when you put in your problem it ask what you want to do with it like , simplify multiply subtract and more but even better you can just take a picture if you dont want to type it is great. The features of this app ends up my struggles in solving mathematical problems, great app really easy to use basically no ads and you can even take pictures of your problems and they will answer really quickly so overall a great app.

## Differentiability and continuity (video)

If the function is undefined or does not exist at a point, then we say that the function is discontinuous. Definition of Differentiability : f ( x) is said to be differentiable at the point x = a ## Continuity and Differentiability (Fully Explained w/ Examples!)

The function is differentiable from the left and right. As in the case of the existence of limits of a function at x 0, it follows that exists if and only if both exist and f' (x 0 -) = f' (x 0 +) Hence if and only if f' (x 0 -) = f' (x 0 +) . If any one

## The function f is differentiable at x if lim

What is Differentiable? A function is said to be differentiable if the derivative of the function exists at all points in its domain. Particularly, if a function f (x) is differentiable at x = a, then f′ (a) exists in the domain. Let us look at some
