Analyzing Function Behavior and Graphs

The video tutorial covers finding local maxima and minima of functions, determining intervals of increase and decrease, and graphing functions. It explains how to use bounds to find these points and how to adjust graphing windows for better visualization. The tutorial also guides on writing intervals for increasing and decreasing functions and concludes with a homework assignment.

What is the purpose of finding local maxima and minima in a function?

• To calculate the function's average value

• To identify intervals of increase and decrease

• To find the function's range

• To determine the function's domain

Which tool is used to find the minimum value of a function on a calculator?

• Graphing tool

• Integral calculator

• Derivative calculator

• Second and Cal functions

Why is it important to adjust the graph window when analyzing a function?

• To view the entire graph

• To change the function's domain

• To alter the function's range

• To simplify the function

What does a decreasing interval on a graph indicate?

• The function's value is oscillating

• The function's value is constant

• The function's value is increasing

• The function's value is decreasing

How do you determine the intervals of increase and decrease?

• By calculating the function's average

• By identifying local maxima and minima

• By using the function's derivative

• By finding the function's zeros

What is the first step in graphing a new function?

• Finding the function's zeros

• Adjusting the graph window

• Calculating the function's derivative

• Identifying the function's range

What should you avoid when setting bounds for finding maxima and minima?

• Setting bounds too close

• Using positive values

• Using negative values

• Crossing a peak or valley
