Formula and method
This calculator uses the values you enter and applies the calculation immediately in your browser. The main output formulas are:
- Average rate of change:
x2===x1 ? NaN : (y2-y1)/(x2-x1)
Some formulas are undefined for certain input combinations, such as division by zero, equal x-values in a slope calculation, or logarithms of non-positive numbers. In those cases the live tool reports that the result is undefined instead of displaying Infinity or NaN.
Examples
- Example: with x1 = 1, f(x1) = 2, x2 = 5, f(x2) = 18, this calculator returns Average rate of change = 4.
