Answer

$x=1$ (multiplicity 1), crosses the x-axis, $x=-2$ (multiplicity 2), touches the x-axis and turns around. $x=-5$ (multiplicity 3), crosses the x-axis,

Work Step by Step

Step 1. Based on the given function, we can identify its zeros as: $x=1$ (multiplicity 1), $x=-2$ (multiplicity 2), $x=-5$ (multiplicity 3). Step 2. For $x=1$ and $x=-5$, the graph crosses the x-axis. Step 3. For $x=-2$, the graph touches the x-axis and turns around.
