Average Rate of Change Calculator
Use JavaScript math syntax: x^2, sqrt(x), log(x), sin(x), etc.
Result
[f(x₂) – f(x₁)] / (x₂ – x₁)
Step 1: f(x₁) = f(1) = 1
Step 2: f(x₂) = f(3) = 9
Step 3: [f(x₂) – f(x₁)] = 8
Step 4: (x₂ – x₁) = 2
Average Rate of Change = 4
What is Average Rate of Change?
The average rate of change between two points on a function represents the slope of the secant line connecting them. It measures how much the function changes per unit on average between the two points.
Formula: [f(b) – f(a)] / (b – a)
