Chapter 2.3, Problem 90AYU

96. Redo Problem 95 with the following additional information: increasing on $(-\infty ,-1]$, $[2,\infty \text{)}$; decreasing on $[-1,\text{ 2]}$. Again compare your graph with others and comment on any differences.

To determine

To graph: To sketch the graph using increasing and decreasing intervals. Comment on any differences.

Answer to Problem 90AYU

Explanation of Solution

Given:

It is given that it is increasing in $(-\infty ,-1]$ and $\left[2,\infty \right)$ and decreasing in $\left[-1,2\right]$.

Graph:

Interpretation:

Decreasing interval range is different in others graph.

The rest are same as compared with mine.
