Please help Thanks

Let p(x) be defined on $2 \le x \le 10$ such that

$p(x) = \begin{cases} x + 1 &\quad \lfloor x \rfloor\text{ is prime} \\ p(y) + (x + 1 - \lfloor x \rfloor) &\quad \text{otherwise} \end{cases}$

where y is the greatest prime factor of $\lfloor x\rfloor.$ Express the range of p in interval notation.
