Section 1: K/U Multiple Choice: [5 Marks] 1. The limx-4-7 a) 4 b) - 7 c) 0 d) Does Not Exist 2. The limx--4+ Vx2 - 16 a) 0 b) 4 c) 16 d) Does Not Exist 3. The limx-0 x-7 x a) 0 b) infinity C) -7 d) Does Not Exist 2x-5 4. The limx-5 x-6 a) 5 b) - 1 c) -5 d) Does Not Exist x-3 5. For what values of x will the function, f(x) = - be discontinuous? x3+3x2-18x a) -6, 0 b) -6, -3,0 C) -6, 0, 3 d) -3, 0, 6 True or False: [4 Marks] 6. If the limit exists at x = a then the function is continuous at x = a. 7. A removable discontinuity is the only discontinuity in which the limit exists. 8. A cusp is not a discontinuity but does result in the derivative not existing. 9. The reason we use the limit as h-+0 to find the slope is because A x -0
