Rates of change question
Use an algebric strategy to verify that the point given for each function is either a maximum or a minimum.
x^33x ; (1, 2)
so i tried finding the instantaneous rate of change before 1 and after 1 to see if its a maximum or a minimum, since if its a local max before 1 would be positive and after would be negative but i couldn't reach the solution in the back of the book. any help would be appreciated.
the formula i used was the difference quotient.
