Chapter 4: Q. 16 (page 241)

Solve the inequality by using the graph of the function.

Solve R(x)<0, whereR(x)=x(x-1)(x+2)

Short Answer

Expert verified

The solution of the inequality is (-鈭�,-2)鈭�(0,1).

Step by step solution

01

Step 1. Given Information 

We are given a function,

R(x)=x(x-1)(x+2)

02

Step 2. Graphing the function  

The graph of the function is as follows,

03

Step 3. Solution of the inequality  

As seen from the graph, R(x)<0for (-鈭�,-2)鈭�(0,1).

Hence the solution is (-鈭�,-2)鈭�(0,1).
