Domain and range:
The domain of a function is all the values the the input assumes.
The range of a function is given by all the values that the output assumes.
In a graphic:
The domain is given by the x-values, the horizontal axis.
The range is given by the y-values, the vertical axis.
In this question:
x, in the horizontal axis, assumes values between -4 and 2.
The closed circle at x = -4 and x = 2 indicates that these values are part of the interval.
Thus, the domain of the graphed function is: [tex]-4 \leq x \leq 2[/tex], and the correct answer is given by option D.

D. [tex]-4 \le x \le 2[/tex]
The procedure of solution consist consist in determine graphically the Domain of the Function shown in the figure. In this case, the Domain is the Set of values of [tex]x[/tex] in Interval notation, which represented in the "horizontal" axis of the Cartesian Plane. Please notice that black points means that given Function includes extreme values.
By visual examination of the function, we conclude that domain of the function is represented by:
[tex]Dom\{f(x)\} = [-4, 2][/tex]
Which is equivalent to the following expression in Inequality notation:
[tex]-4 \le x \le 2[/tex]
Therefore, we conclude that right answer is D.

The Recreation Center has an L-shaped pool. One pool is 8 meters by 6 meters. The other part is 12 meters by 6 meters. The whole pool is 4 meters deep. What is the volume of the entire pool?
Answers
Answer:
480m³
Step-by-step explanation:
The entire pool have the same depth which is 4metres
Since the pool is L shaped, we will find the volume of each part and add them together to get the volume of the entire pool.
Using the formula for calculating volume of a rectangular box
V = lwh
L is the length
w is the width
h is he height
For the first pool.
Length = 8m
Width = 6m
Height = 4m (depth)
Volume = 8×6×4
Volume = 192m³
For the other pool.
Length = 12m
Width = 6m
Height = 4m (depth)
Volume = 12×6×4
Volume = 288m³
Volume of the entire pool = 192+288 = 480m³

If a polynomial has a root of −2, what FACTOR will divide evenly into the polynomial?
Answers
Given:
A polynomial has a root of −2.
To find:
The factor that will divide evenly into the polynomial.
Solution:
We know that, if c is a root of a polynomial P(x), then (x-c) is a factor of polynomial P(x).
we have,
-2 is a root of polynomial.
⇒ (x-(-2)) is a factor of polynomial.
⇒ (x+2) is a factor of polynomial.
⇒ (x+2) will divide the polynomial completely.
Therefore, the factor (x+2) will divide evenly into the polynomial.
The factors of a polynomial divide the polynomial evenly, without remainder
The factor of the polynomial is x + 2
The root of the polynomial is given as:
[tex]\mathbf{Root = -2}[/tex]
Assume the polynomial is a function of x.
i.e. the variable of the polynomial is x
Then the root can be represented as:
[tex]\mathbf{x= -2}[/tex]
Add 2 to both sides
[tex]\mathbf{x + 2= -2 +2}[/tex]
So, we have:
[tex]\mathbf{x + 2= 0}[/tex]
Hence, the factor of the polynomial is x + 2
