For each of the following questions, please select clearly the choice that you feel best answers the question. If necessary, please provide a brief explanation as to why you have selected your choice. McClanahan is asked to find the maximum value for a continuous polynomial function, f(x), restricted to a closed interval asxsb. Rue finds the first-order derivative, f'(x), and discovers that f(x) is equal to zero when x=3, what can Rue McClanahan conclude from this? a) 3 is the maximum value b) f(3) is the maximum value c) the maximum value is obtained when x is as large as possible or when x is as small as possible or when x 3 d) None of these choices (write a brief statement explaining why in the space below)Explanation / Answer
D) None of these Choices. When a first derivative is zero it means it can be either maximum or minimum or inflection point. Nothing can be deduced unless second derivative is found. Double derivative is less than zero means maximum.
