What is Function?The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Here, given function;
f(x) = -x² - 4x + 6
1. If we take -1 common from the given function, we get
f(x) = -1 (x² + 4x - 6)
f(x) = -1 (x² + 4x) + 6
Thus, first block contains -1 and second block contains 4.
2. Then we add half of the coefficient of x², (b/2)², inside the bracket and subtract it outside a times, a(b/2)².
f(x) = -1 ( x² + 2. 2x + 2²) +2² + 6
f(x) = -1 ( x² + 4x + 2²) +4 + 6
Thus, first block contains -1, second block contains 4, third block contains 4, and fourth block contains 4.
3. Then we factorize the bracket and simplify outside the bracket;
f(x) = -1 (x + 2)² + 10
Thus, first block contains -1, second block contains 2 and third block contains 10.

Answers
The correct answer is option D which is the model will be
A = 13000( 0.72 ) [tex].^t[/tex].
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that:-
The cost of the car is $13000.The depreciation is 28%.The expression will be formed as:-
As we can see that the depreciation of the car per year is 28% so the amount of the car is decreased by 28 percent every year.
Now the remaining value of the car will be 100 - 28 = 78%. So the expression will be given as:-
A = 13000( 0.72 ) [tex].^t[/tex].
Therefore the correct answer is option D which is the model will be
A = 13000( 0.72 ) [tex].^t[/tex].

c) Median = the middle age
(but before that, we must arrange the ages either a cording to their sizes either from biggest to smallest (descending order) or from smallest to biggest (ascending order)
so we arrange in ascending order but the numbers are already arranged so we don't have to stress ourselves:

Solve for x (12x-7)/4=(5x+18)/3
Answers
Answer:
Step-by-step explanation:do i know u
Answer:
x= 5.8125
Step-by-step explanation:
Given: [tex]\frac{12x-7}{4} =\frac{5x+18}{3}[/tex]
Since we have one fraction equal to another fraction, we can cross multiply.
(12x -7)(3)= 4(5x +18)
Expand:
36x -21= 20x +72
Bring all the x terms to one side, constant to the other:
36x -20x= 72 +21
Simplify:
16x= 93
Divide both sides by 16:
[tex]x= \frac{93}{16}[/tex]
x= 5.8125

What is the inverse of the function f(x) = 4x + 8?
Answers
Answer: A. h(x) = 1/4x - 2
Step-by-step explanation:
f(x) = 4x + 8
find the inverse...
A.
[tex]h(x) = \frac{1}{4} x-2[/tex]
[tex]f(x) = 4(\frac{1}{4} x-2)+8[/tex]
[tex]f(x)=x-8+8[/tex]
[tex]f(x)=x[/tex]
[tex]h(x) = \frac{1}{4} (4x+8)-2[/tex]
[tex]h(x)=x+2-2[/tex]
[tex]h(x)=x[/tex]
Since they both come out to 'x', they are inverses of each other.
f(x) = 4x + 8 and h(x) = 1/4x - 2 are inverses
Explanation: Interchange X and y
X=4y+8 swap the sides of the equation
4y+8=X Move the constant to the right-hand side and change its sign

The function y = f(x) is graphed below. What is the average rate of change of the
function f(x) on the interval -8 ≤ x ≤ 8?
Answers
The average rate of change of the function is -35/16.
How to find the average rate of change of the function?We have to determine the average rate of change of the function f(x) on the interval -8 ≤ x ≤ 8.
so
at x₁ = -8, f(x₁) = f(-8) = 30
at x₂ = 8, f(x₂) = f(8) = -5
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [f(8) - f(-8) ] / [8-(-8)]
= [-5 - (30)] / [16]
= [-35] / 16
Therefore, the average rate of change of the function is -35/16.

The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
As we know if the f(x) has inverse function g(x)
Let (x, y) satisfy the function f(x) then (y, x) must satify the function g(x)
f(x) has ordered pair = (4, 1)

We have,
A figure which is on a straight line i.e 180°.
Now,
Find the rotations which it will make,
When a person or figure rotates completely i.e. to reach to its original position or shape it makes an angle of 360°.
So,
In the same way;
After rotaions of this figure to reach it to its original position it has to make an angle of 360°.
So,
That means,
First this figure will make a rotation of 60°.
Then it will make a rotation of 120°.
Then it will make a rotation of 180°.
i.e.
The sum of these angles = 60° + 120° + 180° = 360°.
So,
We have to choose that option, in which the sum of angles is 360°.
i.e.
Option 1. ii, iii, and iv.
Therefore, the rotations which will map this figure itself are 60°, 120°, and 180° and these values are given in option i.e. (a) ii, iii, and iv.

Given that the area of the house on a blueprint = is 7 square inches.
The scale of the blueprint = is 1 inch: 6 feet.
Therefore, we would have the following proportion:
