Answer:

Step-by-step explanation:
<u>Polynomials
</u>
a)
The polynomial whose graph is shown is of third degree because it has three real roots. The roots of a polynomial are the values of x that make the expression equal to zero. We can see it happens three times in the graph provided. The roots or zeros are
x=-2, x=1, x=3
b)
The factored form of a polynomial whose roots
are known is

We know the value of the roots, thus the polynomial is written as

We need to find the value of a. We do that by replacing the value of x=0 and finding a that makes f(0)=3 (as seen in the graph). Thus





Thus the factored form of the polynomial is

c)
Let's multiply all the factors





The answer is 1/6 (one-sixth)
Answer:
x ≥ - 53
Step-by-step explanation:
The closed circle at - 53 indicates that x can be equal to this value.
The arrow head points right indicating values greater than - 53.
Answer:
The negative property is a sign used when a number goes below zero
Step-by-step explanation:
if that is the negative you are talking about
