# How To Find Original Function From Derivative

Posted on

An example would be given the derivative is Axn. Do a search for integration to learn more about it. Determine If A Function Is Differentiable Calculus Mathematics Mathematician

### I have a function f of X here and I want to think about which of these curves could represent F prime of X could represent the derivative of f of X well to think about that we just have to think about well what is the slope of the tangent line doing at each point of f of X and see if this corresponds to that slope if the value of these functions correspond to that slope so we can see. How to find original function from derivative. Would be A 1n1 xn1 C some constant. Int fx fx. To find the particular function from the derivation we have to integrate the function.

You can also get a better visual and understanding of the function by using our graphing tool. X 2 9 0 x 3x 3 0. Sign in with Office365.

The problem provides the derivative of the function hence you need to evaluate the function using anti-derivatives such that. D d x f g x f g x g x and the quotient rule and the rule for sums and try to match f and g to functions whose derivatives you know. Plug any critical numbers you found in Step 2 into your original function to check that they are in the domain of the original function.

When you do that youll find out where the derivative is undefined. Choose Find the Derivative. Differentiation and integration are opposite process.

Example 1 What if youre not given the equation of the original function. Find the derivative of f xsqrt x. Take the derivative of the slope the second derivative of the original function.

Compare the resulting derivative to that obtained by differentiating the function directly. If fx mathx2math then fx mathfracx33 cmath where mathcmath is a constant. 1 Graph of Graph of.

The Derivative of 14 10t is 10 This means the slope is continually getting smaller 10. If the derivative. Fx 4x – 5 fx 4x – 5 dx 4x 2 2 – 5x c fx 2x 2 – 5x c —.

Traveling from left to right the slope starts out positive the function rises goes through zero the flat point and then the slope becomes negative the function falls. The best you can do is come up with a range of functions that would have the same derivative. For example given that the derivative of a function is 2x you could use the ddx xn n x n-1 to guess that the original function was x 2 but what would you do if you were told that x 2 itself was the derivative of another function.

For this function the critical numbers. From the topic selector and click to see the result. At this point in your study there are no rules for doing these problems.
