Answer
Increasing: $-1\lt x\lt0$ or $1\lt x$
Decreasing: $x\lt-1$ or $0\lt x\lt1$
Work Step by Step
Increasing means that the derivative of a function, $f'$, is greater than $0$ ($f'\gt0$). That is, the graph of $f'$ is above the x-axis. This happens when $-1\lt x\lt0$ or $1\lt x$
Decreasing means that the derivative of a function, $f'$, is less than $0$ ($f'\lt0$). That is, the graph of $f'$ is below the x-axis. This happens when $x\lt-1$ or $0\lt x\lt1$
