The formula, when distributed is $y = {x}^{3} + 2 {x}^{2}$.
Part a wants us to just think about the highest order term, which we can easily see is ${x}^{3}$. Since for large values of $x$, ${x}^{3} > 2 {x}^{2}$, this is our end behavior: $y = {x}^{3}$
Part b wants us to find where $y = 0$. Using the factored version of the equation, this is very easy to see: $y = {x}^{2} \left(x + 2\right) = 0$ when $x = 0$ or $x + 2 = 0 \implies x = - 2$. Therefore the two x-intercepts are $- 2 , 0$, where it crosses once at $- 2$ but bounces back at $x = 0$.
Part c wants us to find where $x = 0$. As noted above, that's at $y = 0$.
