6. (10 points) Circle True or False: (a) (T/F) The derivative of a linear function is equal to its slope. (b) (T/F) If f'(c) = 0, then f(x) has a local maximum or local minimum at r = c. Furthermore, the value x - c is called a critical point. (c) (T/F) The function f(x) = 2x - 3 x -1 satisfies the hypotheses of the Mean Value Theorem on the interval [-2, 0] (d) (T/F) A function can have more than one antiderivative and more than one derivative. (e) (T/F) It is impossible for a function f to have an absolute minimum on the interval [a, b] if f"
