Chapter 2: Limits and Continuity - Section 2.2 - Limit of a Function and Limit Laws - Exercises 2.2 - Page 56: 2

a.) 0 b) -1 c)undefined d.) -1

a.) the limit as t approaches -2 is 0. We can follow the graph up there from both sides to see this b.) We can see that value as t approaches -1 is -1 c.)The limit is undefined because there are many jumps in the function here. d.)the function is constant from -1 to 0, so the limit as t approaches -0.5 is -1
