Quick Check Exercises pg 152:1,2ab, pg 152 153: 1abcd,4abcd,5,9,10ab,11,13, A. What do limits have to do with continuity? B. On pg 144, three conditions required for f ( x ) to be continuous at a are listed. a. Give an example of a function that satisfies 1 & 2 but not 3. b. Give an example of a function that satisfies 2 but not 1. C. Give two examples of famous functions that are continuous. D. Give two examples of famous functions that are not continuous. E. What’s the difference between being continuous at a point and being continuous on an interval? F. Where are polynomials continuous? G. Where are rational functions continuous? H.
