## Content



This function calculates predicted exponential growth. This function returns the y values for a series of new x values that are specified by using existing x and y values.

## Syntax

GROWTH(*y,x,newx,constant*)

## Remarks

This function has these arguments:

| **Argument** | **Description** |
| -------- | ----------- |
| *y* | Set of y values that are known in the relationship y=b\*m^x |
| x | (Optional) X is an optional set of x values that may be known in the relationship y=b\*m^x |
| *newx* | New x values for which this functions returns the corresponding y values |
| *constant* | Logical value that specifies whether to force the constant b to equal 1 |

If constant is true or omitted then b is calculated normally. If constant is false then b is equal to 0 and the m values are adjusted so that y=m^x.
If x is omitted then x defaults to the array {1,2,3...}, that has the same dimensions as y.
If newx is omitted then it defaults to x.

## Remarks

Use the [INDEX](/spreadnet/docs/latest/online-formula/formulas-functionsall/formulas-functsFtoK/FunctionINDEX) function to get individual elements from the returned array.
