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 a = c. Furthermore, the value x = c is called a critical point. (c) (T/F) The function / (x) = 2x - C - 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 / to have an absolute minimum on the interval Ja, b) if f
