Answer:
The polynomial is:

Step-by-step explanation:
Zeros of a function:
Given a polynomial f(x), this polynomial has roots
such that it can be written as:
, in which a is the leading coefficient.
Zeros of −3, −1, and 2
This means that
. Thus





Passes through the point (1,12).
This means that when
. We use this to find a.




Thus


1/5 of 55=55/5= 11. Hope that helps. ((:
