Answer:
[tex](f \ o \ p)(9) = 4471[/tex]
Step-by-step explanation:
We will assume the black dot between f and p (what we want to find) is a "composition of function".
So, it will mean, put the function p into the function f and then evaluate that at the value of s = 9.
So, lets find the composition first:
[tex](f \ o \ p)(s) = 7(s^3-10s)-2\\(f \ o \ p)(s) = 7s^3-70s-2[/tex]
Now, we put "9" into s and find the value:
[tex](f \ o \ p)(s) = 7s^3-70s-2\\(f \ o \ p)(9) = 7(9)^3-70(9)-2\\(f \ o \ p)(9) = 4471[/tex]
