What is the Average Rate of Change?

In Maths, the average rate of change of a function between two input values is defined as the total change of the output values (function) divided by the change in the input values. Generally, the rate of change defines how one quantity changes in relation to the change in the other quantity. While calculating the average rate of change, how fast the output functional values changes are compared to the input values.

Standard Form

The standard formula to determine the average rate of change is given as follows:

For any function f(x) = y between the value x = a, and x = b, then the formula is

Average Rate of Change = [f(b)-f(a)] / [b-a]

Frequently Asked Questions on The Average Rate of Change Calculator

What is the difference between the rate of change and slope?

The slope of the line represents the rate of change. But the distinct difference between the two is that the rate of change compares the difference between the two measurements, whereas the slope is the strict property of graphed lines.

What does the positive and negative rate of change mean?

The positive rate of change means that the measurement of the quantity is increasing over time. The negative rate of change means that quantity measure is decreasing over time.

What is meant by zero rates of change?

The average rate of change is zero when the sum of all the positive and the negative slope on the given interval will be zero. In this case, f(a) should be equal to f(b). This is known as a zero rate of change.

Average Rate of Change Formula:

For a function, it is the change in the y-value divided by the change in the x-value for two distinct points on the graph.

Formula:

c = (f(A) - f(B)) / (A-B) Where, c = Average Rate of Change e = Expression A = A Value B = B Value

Average Rate of Change of Function: It is the change in the value of a quantity divided by the elapsed time. In a function it determines the slope of the secant line between the two points.

Use our free online average rate of change calculator to find the average rate at which one quantity is changing with respect to an other changing quantity in the given expression (function). In the above calculator enter an expression and the values of A and B and click calculate to find the value of 'Average Rate of Change'.

Example:

Consider an equation 2x³ + 3x + 2, with A value as 3 and B value as 2.Calculate average rate of return of a function.

Solution:

f(a) = 2(3)³+ 3(3) + 2
= 54 + 9 + 2
= 65
f(b) = 2(2)³ + 3(2) + 2
= 16 + 6 + 2
= 24
Hence, average rate change = 65 - 24 / 3 - 2
= 41

How do I find the average rate of change of a function?

The average rate of change formula is used to find the slope of a graphed function. To find the average rate of change, divide the change in y-values by the change in x-values.

How do you find the average rate of change of the function over the given interval?

To find the average rate of change, we divide the change in y (output) by the change in x (input). And visually, all we are doing is calculating the slope of the secant line passing between two points.

What is the average rate of change?

What is average rate of change? It is a measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph. Want to learn more about average rate of change?

How do I find the average rate of change of a function when given a function and two inputs?

The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
