Calculateur de Average Rate of Change
Calculate the average rate of change of a function between two points.
Formula and method
This calculator computes Average rate of change directly in your browser without sending data to an external server.
Mathematical formula
- Average rate of change:
x2===x1 ? NaN : (y2-y1) ÷ (x2-x1)
Variables and parameters
- x1 (x1): default value 1.
- f(x1) (y1): default value 2.
- x2 (x2): default value 5.
- f(x2) (y2): default value 18.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
