.
If = , what is the minimum value of P?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The square root part domain is x >= 5.
So, it is the domain for the entire p(x).
In this domain monotonically grows.
3x monotonically grows too.
Hence, p(x) monotonically grows.
It implies that the minimum value of p(x) is at x = 5. You can easily calculate it.
