Chapter 4: Q. 4 (page 193)

Use graphing utility to approximate (round to two decimal places) the local maximum value and local minimum value of fx=x3-2x2-4x+5, for -3<x<3.

Short Answer

Expert verified

The solution is the local maximum value is6.48at x=-0.67and local minimum value is-3at x=2

Step by step solution

01

Step 1. Given information 

Function:fx=x3-2x2-4x+5for-3<x<3

02

Step 2. Calculation  

Graph of the function fx=x3-2x2-4x+5for -3<x<3is -

So, the local maximum value is 6.48at x=-0.67and local minimum value is-3atx=2.
