#### Answer

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

#### Work Step by Step

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
