(a)[3]
Finish the table.
(b)[4]
On the grid, sketch the graph of $y = x^3 + 3x^2 + 2$ for $-3.5 \le x \le 1.5$.
(c)[1]
Use your graph to solve $x^3 + 3x^2 + 2 = 0$ for $-3.5 \le x \le 1.5$.
(d)[2]
By plotting a suitable straight line, solve $x^3 + 3x^2 + 2x + 2 = 0$ for $-3.5 \le x \le 1.5$.
(e)[1]
For $-3.5 \le x \le 1.5$, the equation $x^3 + 3x^2 + 2 = k$ has three solutions, and $k$ is an integer. Write down one possible value of $k$.
