The appropriate choice is \boxed{\bf option\ B}, meaning that the function's domain is \boxed{(-2,-1,0,1)}.

Further details:

In this case, the function is presented as a collection of ordered pairs detailed in Table 1 (included at the end).

The function can generally be expressed as \{(x,y)|x,y\in\mathbb{R} \}, with x representing the domain of the function, y being the range and \mathbb{R} indicating the set of real numbers.

The domain consists of all points where the function is defined, which includes all potential values of x that yield an output y.

The range refers to all output values of y derived from the specified domain.x

The function is \{(-2,0),(-1,1),(0,2),(1,3)\}.

For different values of f(x), the corresponding outcomes for x can be expressed as follows:

f(-2)=0,f(-1)=1,f(0)=2\text{ and }f(1)=3

Consequently, the domain of the function is (-2,-1,0,1).

Option (A)

In this scenario, the domain is (-2,0),(-1,1),(0,2),(1,3).

The provided domain is represented in function form where x (domain) corresponds to -2,-1,0,1 and y (range) represents 0,1,2,3.

Thus, this representation does not accurately reflect the domain.

The representation corresponds to the ordered pairs that define a function.

Therefore, the option (A) is incorrect.

Option (B)

In this case, the domain is (-2,1,0,1).

Here, the domain of the function \{(-2,0),(-1,1),(0,2),(1,3)\} matches (-2,1,0,1), which coincides with choice (B).

Thus, the option (B) is correct.

Option (C)

In this example, the domain is (0,1,2,3).

And the function's domain \{(-2,0),(-1,1),(0,2),(1,3)\} does not align with the choice (C).

Therefore, the option (C) is incorrect.

Option (D)

Here, the domain is (-2,-1,0,1,2,3).

The function's domain \{(-2,0),(-1,1),(0,2),(1,3)\} does not correspond with option (D).

Thus, the option (D) is incorrect.

The function's domain is \boxed{\bf (-2,1,0,1)}.

Hence, the option (B) is correct.

we know that

The function's domain consists of the x values for which the function is valid, while the range encompasses the values produced by the function

in this problem

The values for the function's domain are (-2,-1,0,1)

The corresponding values for the function's range are (0,1,2,3)

therefore

the selected response is option B

(-2,-1,0,1)

Members of a school club are buying matching shirts. They know at least 25 members will get a shirt. Long-sleeved shirts are $10
babunello [11817]

Answer:

The highest number of long-sleeved shirts that can be ordered is 8

and

The lowest number of long-sleeved shirts that can be acquired is 0

Step-by-step breakdown:

Let y denote the quantity of short sleeves and x indicate the quantity of long sleeves.

According to the stipulated conditions:

Members of a school club are purchasing coordinating shirts. They understand that a minimum of 25 members will opt for a shirt.

therefore, we have;

x+y\geq 25               or

y\geq 25 -x....[1]

Given that long-sleeved shirts are priced at $10 each and short-sleeved shirts at $5 each.

Thus;

The total expense for long sleeves amounts to 10x and

the total cost of short sleeves is 5y

Moreover; the club has a budget that does not exceed $165

therefore;

10x+5y\leq 165 

 5y\leq 165 -10x or

y\leq 33-2x......[2]

By plotting the inequality functions:

Graphing equations [1] and [2] produces a maximum at the coordinates (8, 17)

thus, x= 8.

Taking the minimum value of x =0 results in y falling between 25 and 33.

consequently, the solution space is situated between the intersecting lines to the left.

In conclusion, a maximum of 8 long-sleeved shirts can be obtained, while the minimum number of long-sleeved shirts that can be bought is 0

You’re working in a pharmacy, and are making a table to help with dosage amounts for a certain drug. The recommended dosage is 4
lawyer [12517]

Answer: Children who weigh 10 pounds require 12 teaspoons, those at 15 pounds need 18 teaspoons, and for 30 pounds, it is necessary to have 36 teaspoons.

Step-by-step explanation:

We have a recommended dose of 40 mg per 2.2 pounds of weight, given in three doses throughout the day every 8 hours.

Thus, for a single pound, the daily required dosage is calculated as \dfrac{40}{2.2}=18.18\ ml.

Each individual dose corresponds to \dfrac{18.18}{3}=6.06\ ml of the drug.

This means for one pound, the dosage needed per dose is 6.06 ml.

Thus, for 10 pounds, the calculation is 10 x 6.06 ml = 60.6 ml

To convert ml to teaspoons, knowing that 1 teaspoon equals 5 ml, we find: (60.6 ml ÷ 5) = 12.12 ≈ 12 teaspoons.

For a weight of 15 pounds, the drug requirement is 15 x 6.06 ml = 90.9 ml.

This translates to (90.9 ml ÷ 5) = 18.18 ≈ 18 teaspoons.

For the weight of 30 pounds, it is calculated as 30 x 6.06 ml = 181.8 ml.

Converting this gives us (181.8 ml ÷ 5) = 36.36 ≈ 36 teaspoons.

Therefore, children weighing 10 pounds need 12 teaspoons, those at 15 pounds require 18 teaspoons, and those at 30 pounds need 36 teaspoons.

What is the value of x in the equation 8x – 2y = 48, when y = 4?
tester [12383]

Respuesta:

7

Explicación paso a paso:

8x-2y=48, sustituir y por 4, 8x-2(4)=48, multiplicamos, 8x-8=48, sumamos 8 a ambos lados para deshacernos del -8, 8x=56 y finalmente, dividimos entre 8 para eliminar el 8 de x, x=7.
