To solve the problem shown above you must apply the following proccedure:
 1. You have the following function given in the problem:
 <span> f(x)=x3–3x–2
 2. When you give values to the x and plot each point obtained, you obtain the graph shown in the figure attached.
 3. Based on the graph and analizing the alternate form:
 f(x)=(x-2)(x+1)</span>²
 As you can see, there is two roots x=-1, then, you can conclude that the correct answer is the option b, which is:
 b) -1<span>
 </span>
