If $\mathrm{y}$ varies directly as $(\mathrm{x} + 3)$ and $\mathrm{y} = 8$ when $\mathrm{x} = 1$. What is the value of $\mathrm{y}$ when $\mathrm{x} = 2$ ?

Mark ($✓$) against the correct answer in each of the following:

It is given that y is proportional to $\frac{1}{\left({\mathrm{x}}^3-\mathrm{x}\right)}$. When $\mathrm{x}=2$, we have $\mathrm{y}=2$. If $\mathrm{x}=3$, then the value of y is :
