Graphing logistic functions
WebA logistic growth function in x is a function that can be written in the form f (x) = c / (1 + a⋅bx) (or) f (x) = c / (1 + a⋅e-kx) where the constant c is the limit of growth. If b > 1 or k < 0, these formulas yield logistic decay … WebVerify the data follow an exponential pattern. Find the equation that models the data. Select “ ExpReg ” from the STAT then CALC menu.
