Q. 3 Identifying increasing and decre... [FREE SOLUTION]

Chapter 2: Q. 3 (page 164)

Identifying increasing and decreasing behavior: Use a graphing utility to determine the intervals on which $f (x) = - 4 x^{5} + 25 x^{4} - 40 x^{3}$ is increasing or decreasing.

Short Answer

Expert verified

The function $f (x) = - 4 x^{5} + 25 x^{4} - 40 x^{3}$ is increasing on the interval $(2, 3)$ and decreasing on intervals $(- 鈭�, 2) & (3, 鈭�) .$

Step by step solution

Step 1. Given information.

The given function is $f (x) = - 4 x^{5} + 25 x^{4} - 40 x^{3} .$

Step 2. Graph of function.

Plot the graph of function $f (x) = - 4 x^{5} + 25 x^{4} - 40 x^{3}$ using a graphing utility.

The graph o function state that the function is increasing on the interval $(2, 3)$ and decreasing on intervals $(- 鈭�, 2) & (3, 鈭�) .$
