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.

Hey, it's clear. So when you read here is so we have f of X is equal to I need to the ex minus X cubed We could differentiate when we get beat to the ex minus three X square And to get our second derivative, we just differentiate first we gotta eat the X minus six x We're gonna draw our graph up with them all together at once. So original function enough of X while doing black and I'll look like this are derivative is in red and our second derivative is in green.
