Answer

$-1\leq x\leq3$.

Work Step by Step

Using a graphing device, we graph the inequalities as shown below (the red line is the x-axis). The intersection points show the solution region: $-1\leq x\leq3$. Note that the solution region is below the x-axis because that is where the red graph is larger than the green graph, as given by the inequality.
