Answer:

Horizontal translation of the parent graph

Step-by-step explanation:

<h2><u>Definitions</u>:</h2>

In the <u>vertex form</u> of a quadratic function, f(x) = a(x - h)² + k, where:

  • (h, k) = vertex of the graph
  • <em>a</em>  = determines the width and direction of the graph's opening.

A <u>horizonal translation</u> to the parent graph is given by, y = f(x - h), where:

  • <em>h</em> > 0 ⇒ Horizontal translation of <em>h</em> units to the right
  • <em>h</em> < 0 ⇒ Horizontal translation of |<em>h </em>| units to the left

In the graph of g(x) = (x + 12)², the <u>vertex</u> occurs at point (-12, 0).

While the <u>vertex</u> of the parent graph, f(x) = x² occurs at point, (0, 0).

<h2><u>Answers</u>:</h2>

Since the vertex of g(x) occurs at point, (-12, 0), substituting the value of (<em>h</em>, <em>k </em>) into the vertex form will result into:

g(x) = a(x - h)² + k

g(x) = [x - (-12)]² + 0

g(x) = (x + 12)² + 0

g(x) = (x + 12)²

Therefore, the graph of g(x) = (x + 12)² represents the horizontal translation of the parent graph, f(x) = x², where the graph of g(x) is <em>horizontally</em> translated 12 units to the left.

vodomira [7]

Answer:

Average rate of change from day 2 to day 5 is $43.33/day.

Step-by-step explanation:

Sales on day 2 = 200

Sales on day 5 = 330

Rate of change = \frac{330-200}{5-2} =\frac{130}{3}=43.33

aleksley [76]

Answer:

40kg

20kg

10kg

Step-by-step explanation:

The computation of the food each one is getting as follows

Total weights of all dogs

= 20 kg + 10 kg + 5kg

= 35 kg

And, the food is 70 kg

So, each one is getting

for 20 kg

= 70 ÷ 35 × 20

= 40 kg

For 10 kg

= 70 ÷ 35 × 10

= 20 kg

And, for 5 kg

= 70 ÷ 35 × 5

= 10 kg

Pepsi [2]

Answer:

Question 1. Correct choice A

Question 2 Correct choice A

Step-by-step explanation:

To answer the first question, let's do the following operation, subtract the salary for n years of education with the salary for n-1 years of education:

(125.66x_{2}-846.3) - (125.66x_{1}-846.3)\\

Where:

x_{2} represents n years of education

x_{1} represents n-1 years of education.

Then, solving:

(125.66x_{2}-846.3) - (125.66x_{1}-846.3) = 125.66x_{2}-846.3-125.66x_{1} + 846.

= 125.66x_{2}-125.66x_{1}\\

= 125.66 (x_{2}-x_{1}) Since x_{2} is always a unit greater than x_{1}, its subtraction is always equal to 1.

= 125.66(1)\\ = 125.66

This result shows that the increase for an additional year of education is always equal to the value of the slope of the line, that is, $ 125.66. Therefore the correct option for this question is "A".

In cuano to the second question:

The intersection of the line with the y-axis occurs when the value of x is equal to zero, or in this case, when the years in the collage are 0.

This means that when there are no years of education in the collage, the salary is expected to be equal to the value of the intersection of the line with the axis y, that is, equal to 24,600 thousand dollars.

Then the correct option is A.
