Learn to find max, min and intervals of increasing, decreasing

The video tutorial explains how to read graphs to identify increasing and decreasing intervals. It emphasizes reading from left to right and focuses on X values rather than Y values. The tutorial also covers the concepts of local and absolute maxima and minima, explaining how to determine these points on a graph. The lesson concludes with a brief mention of homework.

How should you read a graph to determine if a function is increasing or decreasing?

• From left to right

• From top to bottom

• From right to left

• From bottom to top

Between which X values does the function decrease according to the second section?

• From 1 to 2

• From 2 to 3

• From 3 to 4

• From 4 to 5

What is the function doing between X values 3 and 4?

• Increasing

• Decreasing

• Undefined

• Constant

What is the term used for the highest point in a function that cannot be exceeded?

• Local Min

• Absolute Max

• Absolute Min

• Local Max

What does it mean when a function is described as 'bounded below'?

• It has a minimum value

• It cannot go lower than a certain point

• It is unbounded

• It has a maximum value
