1. For the function () = + , determine the equation of the tangent line at = 1. 2. Describe three techniques to evaluate a limit algebraically. 3. Describe the conditions required for lim () to exist 4. What are the basic types of discontinuity? Give an example of each. 5. The TTC bus travels from one stop to another in 2 min. Its distance in kilometers, from the first stop, is () = 2 1 /3 3, where is in minutes. When will the bus have a velocity of 0.5 /? 6. During an experiment in physics, a student drops a stone from the top of a building that is 320 m high. After seconds, the stone has fallen a distance of () = 52, 0 8. The function that gives the height of the stone above the ground is () = 320 52. Determine the velocity of the stone at = 5
