Chapter 12.5, Problem 36ES

Generate the graph of $y=f\left(x\right)$ using a graphing utility, and then make a conjecture about the shape of the graph of $y=\kappa \left(x\right).$ Check your conjecture by generating the graph of $y=\kappa \left(x\right).$

$f\left(x\right)=x^3-x\text{for}-1\le x\le 1$
