Estimate the input value(s) where the function has a relative extreme point. Identify each relative extreme as a maximum or minimum, and indicate whether the derivative of the function at that point is zero or does not exist. input value maximum or minimum? derivative X = 4.5 X (smallest value) maximum v zero v X = 6 X minimum v does not exist v X = 1.5 x (largest value) maximum v zero v v 2 X 1.5 3 4.5 6 7.5 9
