Definition. This function returns values from an exponential trend. GROWTH() 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() function to calculate an exponential curve for the existing x-values and y-values.
known_y’s (required). The y-values you already know from the relationship y = b * mx
If the known_y’s array consists of a single column, then each column in the known_x’s array is interpreted as a separate variable.
If the known_y’s array consists of a single row, then each row in the known_x’s array is interpreted as a separate variable.
