[tex]g( \: f(x) \: ) = x[/tex]
And
[tex]f( \: g(x) \: ) = x[/tex]_________________________________
So :
[tex]g(x) = {f}^{ - 1}(x) [/tex]
And
[tex]f(x) = {g}^{ - 1}(x) [/tex]
_________________________________
So to find g(x) , we must find the inverse of f(x) .
Let's do it .....
[tex]f(x) = 8 {x}^{3} + 1 [/tex]
[tex]y = 8 {x}^{3} + 1 [/tex]
Subtract the sides of the equation minus 1
[tex]y - 1 = 8 {x}^{3} [/tex]
Divided the sides of the equation by 8
[tex] \frac{y - 1}{8} = {x}^{3} \\ [/tex]
From the sides of the equation, we take the radical with interval 3
[tex] \sqrt[3]{ \frac{y - 1}{8} } = x \\ [/tex]
[tex] \sqrt[3]{ \frac{1}{8}(y - 1) } = x \\ [/tex]
[tex] \frac{1}{2} \sqrt[3]{y - 1} = x \\ [/tex]
[tex] \frac{ \sqrt[3]{y - 1} }{2} = x \\ [/tex]
So ;
[tex] {f}^{ - 1}(x) = \frac{ \sqrt[3]{x - 1} }{2} \\ [/tex]
Now we find g(x) which is :
[tex]g(x) = \frac{ \sqrt[3]{x - 1} }{2} \\ [/tex]
_________________________________
And we're done.
Thanks for watching buddy good luck.

If f(g(x)) = x and g(f(x)) = x , than [tex]\rm g(x) = \sqrt[3]{\dfrac{x-1}{8}}[/tex] and this can be calculated by finding the inverse of the given function f(x).
Given :
[tex]\rm f(x) = 8x^3+1[/tex]f(g(x)) = x and g(f(x)) = xGiven that f(g(x)) = x it means that:
[tex]\rm g(x) = f^{-1}(x)[/tex]
It is also given that g(f(x)) = x that means:
[tex]\rm f(x) = g^{-1}(x)[/tex]
Now, the inverse of f(x) is given by the following calculation:
[tex]\rm f(x) = 8x^3+1[/tex]
Now, replace f(x) with y in the above equation.
[tex]y = 8x^3+1[/tex]
Now, replace y with x and x with y and evaluate 'y'.
[tex]x = 8y^3 +1[/tex]
[tex]\sqrt[3]{\dfrac{x-1}{8}}=y[/tex]
Now, replace y with [tex]\rm f^{-1}(x)[/tex] in the above equation.
[tex]\rm f^{-1}(x) = \sqrt[3]{\dfrac{x-1}{8}}[/tex]
[tex]\rm f^{-1}(x) = \sqrt[3]{\dfrac{x-1}{8}} = g(x)[/tex]

b. $240.01
c. $259.99
d. $25.03
e. $2497.50
HELP NEEDED RIGHT AWAY PLS DUE NOW!!!!
Answer:
D
Step-by-step explanation:
250/9.99=25.0250... Round it to 25.03
The required converted value is $25.03, which is 250 pesos to U. S. dollars.
As we all know, unit conversion is the process of multiplying a provided quantity by a conversion factor that combines the two interconnected units.
To convert 250 pesos to U.S. dollars, we divide the amount of pesos by the exchange rate.
Here, the exchange rate is given as 9.99 pesos per U.S. dollar.
It is the process of assigning a quantity from one unit of measurement to another.
250 pesos / 9.99 pesos per U.S. dollar = 25.025 U.S. dollars
Rounding this to two decimal places, the conversion is approximately $25.03.
Therefore, the correct option is (d) $25.03.

Answer:
the sum of 1/11 and 5/11 is 6/11
Step-by-step explanation:
the sum would mean addition so
1/11 + 5/11
when adding fractions you don't add the denominator
so then you'd only add 1 + 5 which gets you 6

What is the difference between Glasgow and Copenhagen. (Glasgow= -7.8 Copenhagen=-3.8)
Answer:
Step-by-step explanation:
The difference of the two values is 4 as calculated by subtraction.
An arithmetic operation called subtraction is the process of deleting or removing items from a collection. The negative symbol (-) denotes subtraction.
Subtraction can mean eliminating or lowering physical and abstract quantities utilizing a variety of things, such as fractions, matrices, vectors, irrational numbers, decimals, functions, and however negative integers. it is typically linked with natural numbers in mathematics.There are several significant patterns in subtraction. It is anticommutative, which means that altering the sequence alters the answer's sign. Additionally, it is not associative, which means that when subtracting more than two numbers, the method used matters. 0 is the additive identity, hence subtracting it has no effect on a number. In relation to related operations like addition and multiplication, subtraction also abides by predictable principles.The given values for Glasgow and Copenhagen are given as -7.8 and -3.8 .
Therefore difference = -3.8 - (-7.8) = -3.8 +7.8 = 4

Answer:
D, 110$
Step-by-step explanation:
According to the systematic function, given that the bill as a function is equal to one tenth the quantity of x for kilowatt hours less than or equal to 200, and three twentieths of 200 less than the quantity of x plus 20 for kilowatt hours greater than 200. The answer is 110$ because the question gives us a measure of kilowatts greater than 200 so the second equation is used in the system. Therefore .15(800-200) + 20 = b(800), (.15)600 +20 = 90 + 20 = 110

Sofia wants to rent an apartment. She visits Apartment A which charges $100 for a one-time deposit and $400 per month for rent. She also visits Apartment B which charges $500 for a deposit, but only charges $350 per month in rent. Write and solve an inequality that shows how many months it would take for the total paid to be less for Apartment B.
Credit To: "lublana" On Brainly For This Answer
Answer:
Given that one time charge of appartment "a" = $100
Given that monthly rent of appartment "a" = $400
say the number of months = x
then total cost of the rent for apartment "a" = 100+400x
Given that one time charge of appartment "b" = $500
Given that monthly rent of appartment "b" = $350
then total cost of the rent for apartment "b" = 500+350x
Now we have to make an inequality so that number of months it would take for the total paid to be less for apartment b.
that means 100+400x is less than 500+350x
Hence required inequality is 100+400x<500+350x.
Now we have to solve this inequality.
400x-350x<500-100
50x<400
divide both side by 50
x<8
hence final answer is number of months should be less than 8.
