2. Let be the function defined by for . Let be the function defined by for . No graphing calculator is allowed for this question.
Approximate by using the average rate of change of over the interval . Show the work that leads to your answer.
Write an expression in correct limit notation that represents the statement “The values of can be made arbitrarily close to 4 by taking sufficiently close to 2, but not equal to 2.” Then find the value of the limit.
Find . Then interpret the meaning of the limit in terms of the end behavior of the graph of .
A new function is defined by and for . Find the intervals on which is continuous. Justify your answer. The function is defined for , and the function is defined by assigning the value while keeping for all other .
