The function g is defined as follows for the domain given. g(x) = 2 - 2x , domain = \{- 1, 0, 1, 2\} Write the range of g using

Musya8 [376]

Explanation:

The function is given below as

$g(x)=2-2x$

The set of domains is given below as

$\lbrace-1,0,1,2\rbrace$

Step 1:

Put x=-1

$\begin{gathered} g(x)=2-2x \\ g(-1)=2-2(-1) \\ g(-1)=2+2 \\ g(-1)=4 \end{gathered}$

Step 2:

Put x=0

$\begin{gathered} g(x)=2-2x \\ g(0)=2-2(0) \\ g(0)=2 \end{gathered}$

Step 3:

Put x=1

$\begin{gathered} g(x)=2-2x \\ g(1)=2-2(1) \\ g(1)=2-2 \\ g(1)=0 \end{gathered}$

Step 4:

Put x=2

$\begin{gathered} g(x)=2-2x \\ g(2)=2-2(2) \\ g(2)=2-4 \\ g(2)=-2 \end{gathered}$

Hence,

The range of g(x) using set notation will be

$\Rightarrow\lbrace4,2,0,-2\rbrace$

Hence,

The graph of g(x) is given below as

If a town starts with population of 63,500 that declines by 700 people each year, construct an equation to model its population

ankoles [38]

The equation would be 63500-700x=P, where 63500 is the original population, -700 is the amount the population decreases each year, x is the number of years, and P is the total population.

To answer the second part of the question, plug in 53000 for P and solve for x:

63500-700x=53000

<em>*Subtract 63500 from both sides*</em>

-700x=-10500

<em>*Divide both sides by -700*</em>

x=15

It would take 15 years for the population to drop to 53000.

Hope this helps!!

Write the common rule to describe the translation using coordinate notation.

UNO [17]

The common rule is (x - 1, y + 3) can be used to describe the translation.

Step-by-step explanation:

Step 1:

The point J (-3, -4) becomes $J^{1}$ (-4, -1).

In order to write the rule for translation from J to $J^{1}$ , we subtract the x coordinate of J from $J^{1}$ and subtract the y coordinate of J from $J^{1}$ .

The x coordinate $= -4-(-3) = -4+3 = -1.$

The y coordinate $= -1-(-4) = -1+4 = 3.$

Step 2:

So from the calculations, we get that the x coordinate is subtracted by 1 i.e. $x-1$ and the y coordinate is increased by 3 i.e. $y+3$ .

So the common rule is (x - 1, y + 3).
