Step-by-step explanation:
The given value of P is as follows.
P = 1.06F + 22.18,

or, P' = 1.06
As p' is defined and non-zero. Hence, only critical points are boundary points.
For F = 10, the value of P will be calculated as follows.
P =

= 32.78
For F = 70, the value of P will be calculated as follows.
P =

= 96.38
Therefore, the minimum value of P is 32.78 and maximum value of P is 96.38.
