Answer
Refer to the graph below.
Work Step by Step
The $x$-intercepts of the function's graph can be found by equating each factor to zero then solving each equation to obtain:
\begin{align*}
x-1&=0 &\text{or}& &x+2=0\\
x&=1 &\text{or}& &x=-2
\end{align*}
Thus, the $x$-intercepts are $-2$ and $1$.
The $y$_intercept of the function can be found by setting $x=0$ then solving for $y$:
\begin{align*}
P(0)&=(0-1)(0+2)\\
P(0)&=-1(2)\\
P(0)&=-2
\end{align*}
Thus, the $y$-intercept is $-2$
Create a table of values to obtain the one below.
Then, plot each ordered pair and connect the points using a smooth curve.
Refer to the graph above.
