610-187 is 423 but when you estimate it would be 400 this is your answer
For this case we have the following functions:

We must find
By definition of composition of functions we have:

So:
![(p-9) (x) = x ^ 2-1- [5 (x-1)] = (x ^ 2-1) -5 (x-1)](https://tex.z-dn.net/?f=%28p-9%29%20%28x%29%20%3D%20x%20%5E%202-1-%20%5B5%20%28x-1%29%5D%20%3D%20%28x%20%5E%202-1%29%20-5%20%28x-1%29)
Thus, the correct option is option C.
