The graph of f(x) = (4x² - 16) / (2x - 4) is given below.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Function:
f(x) = (4x² - 16) / (2x - 4)
This can be written as,
f(x) = (2x)² - 4² / (2x - 4) [ a² - b² = (a + b)(a - b) ]
f(x) = (2x - 4)(2x + 4) / (2x - 4)
f(x) = 2x + 4
Now,
We will find the coordinates from the function f(x) = 2x + 4
x = 0, f(x) = 4
(0, 4)
x = 1, f(x) = 6
(1, 6)
x = 3, f(x) = 10
(3, 10)
And so on.....
The graph is given below,
Thus,
The graph of f(x) = (4x² - 16) / (2x - 4) is given below.

The graph of y=x^2-4x by drawing the line y=x-4
Answer:
the graph of y=x^2-4x is parabola as shown in the image
Step-by-step explanation:
The graph of [tex]y = x^{2} -4x[/tex] by drawing the line y=x-4
so this gives us that the line y=x-4 satisfies the equation [tex]y = x^{2} -4x[/tex]
To get points put y = x - 4 in the equation [tex]y = x^{2} -4x[/tex]
so we get x -4 = x( x- 4)
x =1 and x - 4 = 0
from here we get x = 1,4
now put these values in y = x -4
From here we get y = -3,0
so the points are (1 , -3) and ( 4 , 0)
Plot these on graph and we get the straight line .
For equation [tex]y = x^{2} -4x[/tex]
As we know it is of type of parabola with shifted centre.

Based on the calculations on these invertible functions, f⁻¹(f(6.022)) is equal to 6.022 and f⁻¹(-10) + f(-6) is equal to -16.
What is an invertible function?An invertible function refers to a type of function that is obtained by reversing the operation of a given function (f(x)).
In Mathematics, a function and its inverse function has the following property f⁻¹(f(x)) = x. By applying this property, we have:
f⁻¹(f(6.022)) = 6.022.
From the table, we have:
f⁻¹(-10) = -6
f(-6) = -10
Therefore, f⁻¹(-10) + f(-6) is given by:
f⁻¹(-10) + f(-6) = -6 - 10
f⁻¹(-10) + f(-6) = -16.

A company makes 140 bags. 39 of the bags have buttons but no zips. 21 of the bags have zips but no buttons. 23 of the bags have neither zips nor buttons. How many bags have zips on them?
Subtraction is a mathematical operation that reflects the removal of things from a collection. The number of bags that zips on them is 78.
What is subtraction?Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.
Given the number of bags that the company makes is 140. 39 of the bags have buttons but no zips. 21 of the bags have zips but no buttons. 23 of the bags have neither zips nor buttons.
Bags that have both zip and button
= Total number of bags - Number of bags with zips but no buttons - Number of bags with buttons but no zips - Number of bags with nor zips nor the buttons
= 140 - 21 - 39 - 23
= 57
Now, the number of bags that has zips will be the bags that only have zips and the number of bags that has zips and buttons. Therefore, the number of bags with zips is,
n = Bags that have both zip and button + Number of bags with zips but no buttons
= 37 + 21
= 78
Hence, the number of bags that zips on them is 78.

Answer:
Bags with zip = (bag with button and zip) + (bag with no button but only zip)
i.e.,
Rotal bags – (bags with neither of two + bags with only buttons)
=> 140-(39+23)
=> 140-62
=> 78
So, 78 bags have zips on them.
Solve for 'x' in the following equation, explaining each step.
3^ (-3x+7) = 3^ (7x-13)
Answer:
x = 2
Step-by-step explanation:
In order to have the two sides of the equation be equal, the exponents must equal.
-3x + 7 = 7x - 13
Add 3x to both sides.
7 = 10x - 13
Add 13 to both sides.
20 = 10x
Divide by 10.

Hello!
The sum of all angles in a triangle is 180°.
Add up all the angles and solve for x by setting the equation to 180°.
Solve for x∠a + ∠b + ∠c = 180°(48 - x)° + (9x - 38)° + 90° = 180°10° + 8x + 90° = 180°8x = 180° - 90° - 10°8x = 80°x = 10°Now that we solved for x, we can plug it back into each equation to solve for each angle.
