Work Step by Step
Step 1. This is a polynomial function with zeros at $x=-2, 1$
Step 2. At $x=-2$, the multiplicity is $2$, so the curve will touch the x-axis and turn around
Step 3. At $x=1$, the curve will across the x-axis.
Step 4. End behaviors:
$x\to-\infty, y\to -\infty$, $x\to\infty, y\to \infty$
Step 5. Y-intercept: $y=(-1)(2)^2=-4$
Step 6. Use the above results and test points as necessary to obtain a graph shown in the figure.
