Students do find it difficult to understand the average rate of change, for example, if you are planning to travel from a “city A” to a “City B”. The distance between the two cities is around 200 Km, you want to cover this distance in around 3 hours. It is quite necessary for you to reach at the time, at what speed you need to travel to reach at the time. You can also use the definite online derivative calculator by calculatored to find the average graph required to reach your destination.

**In this article, we are going to define how you can interpret a graph.**

**How do we find the average rate of change of function?**

Now when we draw a graph between the distance and the time taken to reach the destination, We can find the average speed to reach the destination by the graphical method

The average speed Δ V= ΔS/Δt

Δ V= ΔS2- ΔS1/ Δt2- Δt1

Where The Greek letter Delta, represents the total change in a quantity. The differentiation calculator can automatically find the rate of the function.

● Derived function is f(ΔV),

● Two known functions are f(ΔS) and f(Δt).

**Linear functions:**

When we draw a graph there comes a straight line, by joining the points of both the known quantities at various points. The linear functions are represented by a linear equation. The linear function graph is a straight line like mentioned above. You need to use a derivative calculator to find the average change.We normally use the word slope “m” for describing the gradient of the line. It can be expressed as:

** **** ****Slope=m= Vertical change/Horizontal change**

**The nonLinear functions:**

When we work with the average rate of change calculus** **of nonlinear functions, we will find the slope “m” is not a constant quantity.

** Slope=m= Vertical change/Horizontal change**

* Slope=m= *y2-y1/x2-x1 is not equal to a constant quantity, in the no-linear functions the slope of the line is a secant line, intersecting both the y-axis and the x-axis on the graph. When we are plotting the graph for the no-linear functions, we find the point where the output( y-axis) changes as compared to the input (x-axis). The Online derivative calculator** **would automatically enable us to find the value of the nonlinear function. The value of the slope is always changing with changing inputs and outputs.

**Where can we use the average rate of change?**

Students may find it difficult, where we can use the average rate of change, we can use it to find how function A is changing relative to function B. This average rate of change calculus** **can only be done if we know the values of the input and the output. Then we plot the graph to find the equation of the derived function C, whether it is linear or a nonlinear function. We can predict the value of the derived quantity at a certain point, as we know the value of the slope or gradient at that particular time. You can use the online derivative calculator to find the values instantaneously.

**Conclusion:**

Find the online derivative calculator**, **to perfectly determine the average rate of linear functions. Remember, when working with the linear function as mentioned above, the slope(m) is always a constant. The constant “m” representing the slope is a straight quantity.
