The zeros of a function f(x) are the values of x that cause f(x) to be equal to zero
There are many theorems to find the zeros of the polynomial functions and one of them is
The Factor TheoremThe Factor Theorem can be used
to analyze polynomial equations. By it we can know that there is a relation between factors and zeros.
<span>let: f(x)=(x−a)q(x)+r.
</span>
If a is one of the zeros of the function , then the remainder r =f(a) =0
and <span>f(x)=(x−a)q(x)+0</span> or <span>f(x)=(x−a)q(x)</span>
Notice, written in this form, x – a is a factor of f(x)
the conclusion is: if a is one of the zeros of the function of f(x),
then x−a is a factor of f(x)
And vice versa , if (x−a) is a factor of f(x), then the remainder of the Division Algorithm <span>f(x)=(x−a)q(x)+r</span> is 0. This tells us that a is a zero.
So, we can use the Factor Theorem to completely factor a polynomial of degree n
into the product of n factors. Once the polynomial has been completely
factored, we can easily determine the zeros of the polynomial.
Answer:
4.5
Step-by-step explanation:
Use the distance formula to get sqrt(2^2+4^2) or sqrt20, which is 2sqrt5. sqrt5 is approximately 2.236, so 2*2.236 is 4.472 or 4.5.
lol am I sry I have no idea
You mean crying?
Well, there's a wide range of reasons why the dog is whimpering.
I'd personally contact a vet or do some research.
Although, it may be anxiety or somethiing.
