O A. R(x) does not have an inverse function, because its graph fails the
vertical line test
B. f(x) does not have an inverse function, because its graph fails the
horizontal line test
O C. Rx) has an inverse function, because its graph passes the vertical
line test
OD. Rx) has an inverse function, because its graph passes the
horizontal line test.
Answers
Answer: B
Step-by-step explanation:
The solution is : B. f(x) does not have an inverse function, because its graph fails the horizontal line test.
What is graph?In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.
here, we have,
here, we have,
In the graph, we can see two asymptotes at x = 1.
This means that the denominator is equal to 0 when x = 1, then we can write:
f(x) = A/(x - 1)
Where we can start thinking that A is a constant.
Now we also can see that when x = 2, f(2) is equal to 1, or:
f(2) = 1.
Then:
f(2) = 1 = A/(2 - 1) = A/1
Then we have A = 1.
Then our function is:
f(x) = 1/(x - 1)
Hence, The solution is : B. f(x) does not have an inverse function, because its graph fails the horizontal line test.

Answer:
8/8 , 12/12, 16/16
Given:
A fraction 4/4.
To find:
An equivalent fraction to a given fraction.
Solution:
A fraction equivalent to 4/4 is 8/8.
To answer this question, first of all, we should know that the equivalent fractions of a number or value are the fractions having different numerators and denominators but when simplified they are all equal to the same value or number.
There is no limit to equivalent fractions of a given number.
Now,
we have,
a fraction 4/4,
To get its equivalent fraction, we will multiply the same number in its numerator and denominator.
Let's multiply 2 in both numerator and denominator of 4/4.
We get
4x2/4x2 = 8/8
So, an equivalent fraction to 4/4 is 8/8.
In notice of this 12/12 and 16/16

A movie theater sells two sizes of popcorn, large and small, in bags shaped like rectangular prisms. The small bag has a height of 5.5 inches, a length of 5 inches, and a width of 3 inches. The large bag has the same width and length as the small bag, but two times the volume. What is the height of the large bag of popcorn?
Answers
the solution is:
u should at the first find the volume of the small bag that V= LWH ( Lenght, width, height)
so it will be 82.5
since the Volume of the large bag is 2 times the volume of the small bag so the volume of large bag will be 165
so H = V / LW
H = 165 / 5×3
H = 165 / 15
So the Answer is H = 11

What is a sector of a circle?A sector of a circle is a portion or part of a circle that is composed of an arc and its two radii.
Given that a circle L, we radius 9 and a central angle of 120°, we need to find the area of the sector, which is intercepted by the central angle,
So,
The area of a sector of a circle = central angle / 360° × area of the circle,
So,
A = 120°/360° × π × 9²
