How does the graph of g(x) = (x + 4)3 − 5 compare to the parent function f(x) = x3
vodka [1.7K]

Transforming the function using f(x - h) shifts its graph h units to the right. Here, we have h = -4, so the graph exists shifted 4 units to the left.

<h3>What are transforming functions?</h3>

The transformations of functions describe how to graph a function that exists moving and how its shape exists being changed. There exist basically three kinds of function transformations: translation, dilation, and reflection.

Let f(x) = x³ be the original function.

When -5 exists added to the y-value, it moves the point on the graph down 5 units. Compared to f(x), g(x) exists 5 units down.

f(x) = (x + 4)³ - 5

= [x- (- 4) ]³ - 5 (shift 4 units in the negative x direction that exists 4 units left)

Transforming the function using f(x - h) shifts its graph h units to the right. Here, we have h = -4, so the graph exists shifted 4 units to the left.

1/2x+1/3y=2
timofeeve [1]

Answer:

x=2

y=3

Step-by-step explanation:

x/2+y/3=2   so      

3x/6+2y/6=12/6

then multiply by 6

<em>3x+2y=12</em>    

equation number 2

x/3+y/2=13/6

2x/6+3y/6=13/6

multiply by 6

<em>2x+3y=13</em>

so the system is now

<em>3x+2y=12</em>  

<em>2x+3y=13</em>

<em>from the first equation 2y=12-3x,  y=6 -  3x/2</em>

<em>then put  y in  the second equation</em>

<em>2x+3*(6-3x/2)=13</em>

<em>2x+18-9x/2=13</em>

<em>2x-9x/2=13-18</em>

<em>4x/2-9x/2=-5</em>

<em>-5x/2=-5</em>

<em>*(-1/5)    *(-1/5)</em>

<em>x/2=1</em>

<em>*2    *2</em>

<em>x=2</em>

<em>so y=6-3*2/2=6-3</em>

<em>y=3</em>

<em></em>

<em></em>

<em></em>

A sample has a mean of M = 90 and a standard devia-tion of s 20.=a. Find the z-score for each of the following X values.X = 95X
sladkih [1.3K]

Answer:

\begin{gathered} X=95,z=0.25 \\ X=80,z=-0.5 \\ X=98,z=0.4 \\ X=88,z=-0.1 \\ X=105,z=0.75 \\ X=76,z=-0.7 \end{gathered}

Explanation:

Given a sample with the following:

• Mean,M = 90

,

• Standard deviation, s = 20

To find the z-score for each of the given X values, we use the formula below:

\begin{equation*} z-score=\frac{X-\mu}{\sigma}\text{ where }\begin{cases}{X=Raw\;Score} \\ {\mu=mean} \\ {\sigma=Standard\;Deviation}\end{cases} \end{equation*}

The z-scores are calculated below:

\begin{gathered} \text{When X=95, }z=\frac{95-90}{20}=\frac{5}{20}=0.25 \\ \text{When X=80, }z=\frac{80-90}{20}=\frac{-10}{20}=-0.5 \\ \text{When X=98, }z=\frac{98-90}{20}=\frac{8}{20}=0.4 \end{gathered}\begin{gathered} \text{When X=88,}z=\frac{88-90}{20}=\frac{-2}{20}=-0.1 \\ \text{When X=105, }z=\frac{105-90}{20}=\frac{15}{20}=0.75 \\ \text{When X=76, }z=\frac{76-90}{20}=\frac{-14}{20}=-0.7 \end{gathered}
