LOGEST(Y, X,C,stats)
Where Y is the set of y-values and X is an optional set of x-values in the relationship y = b*m^x.
C is a logical value specifying whether to force the constant b to equal 1 and stats are a logical value specifying whether to return additional regression statistics.This function calculate an exponential curve that fits your data and returns an array of values that describes the curve.
· If you have only one independent x-variable, then you can obtain the y-intercept (b) values directly by using the following formula:
Y-intercept (b):
INDEX(LOGEST(Y, X),2)
· Use y = b*m^x equation is to predict future values of y
