Answer:
Cubic polynomial function with zeros 3,3 and -3 is 
Step-by-step explanation:
We need to find a cubic polynomial function with zeros 3,3 and -3.
If zeros of polynomial are: 3,3,and -3
we can write:
x=3, x=3, x=-3
Or
We can write:
x-3=0, x-3=0, x+3=0
Now, we can write them as:
(x-3)(x-3)(x+3)=0
Multiplying the terms, we can find the polynomial:

So, cubic polynomial function with zeros 3,3 and -3 is 
-18x
you first times the numbers, which becomes -18
Next you add the exponent from the veriables (x) (if you're diving you're subtractiong example: x^a/x^b = x^a-b)
Sooo when you add them you get 8-7=1 which means.. x^1 (but you don't need to put the 1)
-18x
