Answer:

Function g(x) is function f(x) vertically stretched by a factor of 6, reflected in the x-axis, and translated 2 units up.

Step-by-step explanation:

The graph of function f(x) is the <u>parent function</u>.

(Parent functions are the simplest form of a given family of functions).

The graph of g(x) is related to the graph of f(x) by a <u>series of transformations</u>.  To determine the series of transformations, work out the steps of how to go from f(x) to g(x).

<u>Step 1</u>

Starting with the parent function x³, multiply by 6:

\implies 6f(x)=6x^3

Therefore, this is a <u>vertical stretch by a factor of 6</u>.

<u>Step 2</u>

Now make 6x³ negative:

\implies -6f(x)=-6x^3

Therefore, this is a <u>reflection in the x-axis</u>.

<u>Step 3</u>

Finally, add 2:

\implies -6f(x)+2=-6x^3+2

Therefore, the function has been <u>translated 2 units up.</u>

Therefore, function g(x) is function f(x) vertically stretched by a factor of 6, reflected in the x-axis, and translated 2 units up.

What is the vertex of the graph of the function below? y = x2 - 8x + 12 A. (-2, 0) B. (-4, -4) C. (-4, 0) D. (-2, -4)
mario62 [17]
To find the vertex of the parabola, we need to write it in a vertex form.

y=x² - 8x +12 

1) complete the square

y=x² - 8x +12 
y = x² -2*4x + 4² - 4² +12
y=(x-4)²  -16 +12

2) calculate and write a vertex
y=(x-4)²  -16 +12
 y=(x-4)²  - 4

(x-4)           -----     x- coordinate of the vertex x=4
 y=(x-4)²  - 4    -------y- coordinate of the vertex  y = -   4 
  
Vertex is (4, -4).
Answer is (4, -4).  No correct answer is given in choices.

A photocopier makes copies that are 40% larger than the original.
iragen [17]

The length of the copy is 16.8 cm ,The length of the original is 25 cm.

<h3>What is Percentage ?</h3>

Percentage is a number or ratio that represents a fraction of 100

It is given that

A photocopier makes copies that are 40% larger than the original.

An original is 12cm long. Find the length of the copy.

The copy will be

140 % of 12 cm

140 * 12/100

16.8 cm

Therefore , the length of the copy is 16.8 cm.

A copy is 35cm long. Find the length of the original.

The original will be x

140 * x / 100 = 35

x = 35 * 100 / 140 = 25cm

The length of the original is 25 cm.
