We are given the following coordinates:
(0,6), (π/2, 7); (π, 8); (3π/2, 7); and (2π, 6)
If we graph these points, we will observe that the function is a cosine function. Since the function does not pass through the origin. Instead, it has a y-intercept equal to 6. <span />
Factorization involves representing an expression with smaller terms.
- <em>When the greatest common factor is factored out, the equivalent expression is: </em>
<em>.</em> - <em>The complete factored expression is: </em>
<em />
The expression is given as:

The GCF of
and
is
.
So, we have:

Factor out 

To factorize the expression completely, we express
and
as squares.
So, we have:

Apply difference of two squares

So, the complete factor of
is

The answers are:
__________________________
[B]: "√12 " ; AND:
__________________________
[D]: "<span>√20" .
__________________________
Note: "Irrational numbers" have decimals that are: 1) non-terminating; AND: 2) non-repeating.
__________________________
Consider the answer choices given; and consider the given information that there "should be no more than one answer.
__________________________________
Consider the following answer choices:
__________________________________
Choice A) "</span><span>√9" = 3 . Rule out this choice.
__________________________________
Choice C) "</span><span>√16" = 4 . Rule out this choice.
__________________________________
Choice E) "</span><span>√25" = 5. Rule out this choice.
_________________________________
We are left with 2 (two) remaining answer choices:
[B]: "</span>√12" ; and: [D]: "<span>√20" .
_________________________________
If there are more than one answer, then these two choices should be the correct answer. However, let us explore these two choices, using a calculator.
____________________________
[B]: </span>"√12" = 3.4641016151377546
[D]: "√20" = 4.4721359549995794
_________________________________
These two answer choices should the correct answers.
