Answer
Increasing: $x\lt1$
Decreasing: $1\lt x$
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 $x\lt1$
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 $1\lt x$
Increasing: $x\lt1$
Decreasing: $1\lt x$
