| | | This function can return an array |
| | | If "known_y's" is in a single column, then each column of known_x's is interpreted as a separate variable. |
| | | Calculates predicted exponential growth by using existing data. This function returns the y-values for a series of new x-values that you specify by using existing x-values and y-values. You can also use the GROWTH worksheet function to fit an exponential curve to existing x-values and y-values. |
| | | If "known_y's" is in a single row, then each row of "known_x's" is interpreted as a separate variable. |
| | | If any of the numbers in "known_y's" is 0 or negative, then #NUM! is returned. |
| | | The "known_x's" can include one or more sets of variables. If only one variable is used, known_y's and known_x's can be ranges of any shape, as long as they have equal dimensions. If more than one variable is used, known_y's must be a vector (that is, a range with a height of one row or a width of one column). |
| | | If known_x's is omitted, it is assumed to be the array {1,2,3,...} that is the same size as known_y's. |
| | | The "new_x's" must include a column (or row) for each independent variable, just as known_x's does. So, if known_y's is in a single column, known_x's and new_x's must have the same number of columns. If known_y's is in a single row, known_x's and new_x's must have the same number of rows. |
| | | If "new_x" is left blank, it is assumed to be the same as known_x's. |
| | | If "known_x's" and "new_x's" are left blank, they are assumed to be the array {1,2,3,...} that is the same size as known_y's. |
| | | If "const" = True, then b is calculated normally. |
| | | If "const" = False, then b is set equal to 1 and the m-values are adjusted so that y = m^x. |
| | | If "const" is left blank, then True is used. |
| | | Formulas that return arrays must be entered as array formulas after selecting the correct number of cells. For more information about entering array formulas, click . |
| | | When entering an array constant for an argument such as known_x's, use commas to separate values in the same row and semicolons to separate rows. |
