You know the following statement is true: If f(x) is a polynomial, then f(x) is continuous. Which of the following is also true, which is false? (a) If f(x) is not continuous, then it is not a polynomial. (b) If f(x) is not a polynomial, then it is not continuous. (c) If f(x) is continuous, then it is a polynomial. If false, graph a counterexample. True or False. If f(x) is continuous on a closed interval, then it is enough to look at the points where f '(x) = 0 in order to find its absolute maxima and minima. Justify your answer. If the u-substitution u = 3x - 4 is used to evaluate the definite integral f f(x) dx, what are the new limits of integration
