When is a function continuous? 5. Know about limits at infinity. (horizontal asymptotes) 6. Know about functions that have infinite limits. (vertical asymptotes) 7. What are the different techniques for finding the limit? Rates of Change, Slopes, and the Derivative. 1. What is a rate of change of a function, how does it relate to the slope? 2. What is the equation of the slope between two points on a function, what is the difference quotient? 3. How do you find the derivative at a point from the difference quotient? 4. What does the derivative measure? Is the derivative of a function also a function? 5. Find the derivative of different functions using the difference quotient.
