This worksheet introduces the limit laws and asks the student to evaluate two limits by justifying each step with one of the laws. Then the student is asked to evaluate some limits using some limits that are provided. Finally, the student is asked to evaluate some limits using graphs of functions.
This is appropriate for both AP Calculus AB and BC. I usually use this near the beginning of a unit on limits.
An answer key is included.
