The video tutorial introduces Section 46, focusing on graphing with a combination of calculus and calculators. It emphasizes the importance of using graphing calculators in conjunction with calculus to solve complex problems. The tutorial provides examples of graphing functions, finding extrema, and analyzing concavity using both manual and calculator methods. It highlights the use of first and second derivatives for identifying relative extrema and points of inflection. The session concludes with a review of key concepts and a homework assignment.

Why is it important to learn graphing with calculus and calculators before exams?

• It is a fun activity to do before exams.

• It is a requirement for passing the course.

• It allows students to use calculators effectively during exams.

• It helps in understanding the theory better.

What is the new approach to graphing introduced in Section 46?

• Using only calculus to graph functions.

• Using only calculators to graph functions.

• Combining calculus and calculators for graphing.

• Avoiding the use of any technology in graphing.

What is the first step in graphing a polynomial function using a calculator?

• Calculating the second derivative by hand.

• Finding the first derivative by hand.

• Entering the function into the calculator's Y= menu.

• Setting the window to Zoom Fit.

Why should Zoom Fit be avoided when setting the window for graphing?

• It provides an inaccurate representation of the graph.

• It is too complicated to use.

• It requires manual adjustments.

• It is not available on all calculators.

How can you find relative extrema using a graphing calculator?

• By using the Zoom Fit option.

• By guessing the values.

• By using the calculator's minimum and maximum functions.

• By manually calculating the second derivative.

What is the purpose of finding the second derivative when analyzing a graph?

• To determine the function's increasing and decreasing intervals.

• To find the function's points of inflection and concavity.

• To calculate the function's maximum and minimum values.

• To simplify the function's equation.
