The polynomial is: 
Step-by-step explanation:
We need to write a polynomial f(x) that meets the given conditions: Degree 3 polynomial with zeros 3,-5,4
Since zeros are at 3,-5 and 4
So, x=3, x=-5 and x=4
or:
x-3=0, x+5=0 and x-4=0
Multiplying all factors to find the polynomial:

So, the polynomial is:
