Justify your answer with either an example or a counter-example. (a) When a continuous function is deﬁned over a ﬁnite interval, that function always attains its absolute maximum and absolute minimum values on that interval. (2 marks) T F [3:] (b) If f(x) does not exist at the point x = c, then f'(x) does not exist at x = c. (2 marks) (c) Given a function f (x) on an open interval, with c in the domain of f , all numbers 0 for which f ' (c) = 0 or f '(c) does not exist indicate either a maximum, minimum or inﬂection point in the function f (x). (2 marks) Page 2 of 9 pages r—r-—————f (d) Whenever f "(c) = 0 , with c in the domain of f , the function f (x) has an inﬂection point at x = c. (2 marks) T F E3: (e) If f (x) = l on the interval [0, b] when a = —l , b =1, then there exists a number x a < c < b, such that f'(c) = w is veriﬁed. —a (2 marks) (t) The equation x3 + 9x2 + 33x —8 = 0 has exactly one real root. (2 marks) (g) A function g , deﬁned for all positive real numbers, satisﬁed the following two 7 conditions 3(1) :1 and 8'02) = x3 for all .r > 0. Then 8(4) 2 4 7+6.

The velocity of a weight suspended on a spring is given by V(t) = 38in! + 4cost , I Z 0. At time I = 0, the weight is one unit below the equilibrium position. (a) Determine the position of the weight at any time :2 0 . /////// // / / / (7 marks) (b) What is the weight’s maximum displacement from the equilibrium position? (Note: The motion of the weight is called the spring harmonic motion.) (10 marks) Page 6 of 9 pages r———— 5. (a) If the volume enclosed by the surface generated by revolving the region (2 between the curves y = x2 and y = 2-— | x] about the/:2}: -axis is El?— cubic units, ﬁnd the centroid of the region (2 using Pappus’s theorem. (10 marks) Page 7 of 9 pages (b) A ball of radius Q is cut in two pieces by a horizontal plane (1 units above the center of the ball. Determine the volume of the upper piece by using the Shell method. (9 marks) Page 8 of 9 pages 6. Water ﬁlls a tank in the shape of a right~circular cone with top radius 3m and depth 4m. How much work must be done (against gravity) to pump all the water out of the tank over the top edge of the tank? (16 marks) Page 9 of 9 pages ...
