Answer:
One possible polynomial is given by: 
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.
Single root at 0, double root at 3:
This means that:

Decreases as x approaches infinity.
This means that the leading coefficient should be negative. I am going to use -1. So

The answer that I chose was A because it is remotely close to the real answe
Answer: A) -1
Step-by-step explanation:
Answer:50,000+600+70+9
Step-by-step explanation:
So you add all of the numbers, but instead of adding all of them together you put the zeros in place of the other numbers. For example, if you have 76,546 you would write it like this, 70,000+6,000+500+40+6
