Algebra 2 help please :( Polynomials

Question

N=4, -4, 1/3, & 2+3i are zeros f(1)=100 

Answer 1

if those 4 values are zeros then we can back track the factored forms of those zeros which are

(n-4),(n+4),(3n-1),(n-3i-2). 

If you set these equal to 0 individually and solve for n, then you get the same zero values.

If you want to find out the original function, the equation for what the f(n) looks like, then simply foil all those 4 factored ones one at a time and you will get a long equation which you can combine the like terms to shred it down to the function f(n).
