What is Meant by Instantaneous Rate of Change?

In Mathematics, the instantaneous rate of change is defined as the change in the rate at a particular point. It is same as the rate of change in the derivative value of a function at a specific point. If the graph for the instantaneous rate of change at a specific point is drawn, the obtained graph is the same as the tangent line slope.

Example

Question:
Find the instantaneous rate of change for the function y= 3x2– 2x at x = 2
Solution:
Given Function: y= 3x2 – 2x
The instantaneous rate of change is:
dy/dx = 6x-2
When x = 2, it becomes
= 6(2) – 2
=10
Hence, the instantaneous rate of change is 10 for the given function when x=2
