| Name | Type | Description |
| arg1 | ApiRange | Array.<number> | The set of y-values from the y = b*m^x equation, an array or range of positive numbers. |
| arg2 | ApiRange | Array.<number> | An optional set of x-values from the y = b*m^x equation, an array or range of positive numbers that has the same size as the set of y-values. |
| arg3 | ApiRange | Array.<number> | New x-values for which the function will return the corresponding y-values. |
| arg4 | boolean | A logical value: the constant b is calculated normally if this parameter is set to true, and b is set equal to 1 if the parameter is false or omitted. |
