In mathematics, a derivative is a measure of how a function changes as its input changes. Loosely speaking, a derivative can be thought of as how much one quantity is changing in response to changes in some other quantity; for example, the derivative of the position of a moving object with respect to time is the object's velocity. The concept of a derivative developed as a way to measure the steepness of a curve; the concept was ultimately generalized and now "derivative" is often used to refer to the relationship between two variables, independent and dependent, and to various related notions, such as the differential.

In mathematics, the derivative of a function of a real variable measures the sensitivity to change of the function value (the rate of change of the value of the function). If the derivative of a function at a chosen input value equals a constant value, the function is said to be a constant function. In this case the derivative itself is the constant of the function, and is called the constant of integration.

so of interest here is the derivative of this function. F of X is three over x. So one way toe approaches is to realize that three other ex, um, is the same as three X to the power minus one. So knowing that we can define the derivative, it's gonna be minus one times three X to the minus two. Okay, which is minus three. Well, that s got okay. So if you know how to derivative of father function, then you can easily find the derivative of it inverse function. One of the extent is and this is the value.
