By functional theory, we conclude the function described in a table, whose domain is x ∈ [-1, 1] (-1 ≤ x ≤ 1) and whose range is y ∈ [3, 7] (3 ≤ x ≤ 7)

<h3>What are the domain and the range of a given function?</h3>

Relations are formed by two sets of values, an <em>input</em> set named domain and an <em>output</em> set named range. Functions are relations such that every element of the domain has only one element of the range.

In this question we show a function describe in a table, whose domain is x ∈ [-1, 1] (-1 ≤ x ≤ 1) and whose range is y ∈ [3, 7] (3 ≤ x ≤ 7).

Answer: Option 'B' is correct.

Step-by-step explanation:

since we have given that

Time taken to build a cabinet by Genna = 4 hours.

Time taken to build a cabinet by Claude = 3 hours

Now, time taken by both Genna and Claude to build a cabinet together is to be find.

Work done by Genna is given by

\frac{1}{4}

Work done by Claude is given by

\frac{1}{3}

According to question,

\frac{1}{4}+\frac{1}{3}=\frac{1}{x}\\\\\frac{3+4}{12}=\frac{1}{x}\\\\\frac{7}{12}=\frac{1}{x}\\\\x=\frac{12}{7}\\\\x=1\frac{5}{7}\ hours

Hence, Option 'B' is correct.

Please help me thanks sooo much

Answer:

P = 21x + 4

Step-by-step explanation:

The perimeter is the length of all the sides added up.

(3x) + (4x + 1) + (2x - 2) + (2x - 2) + (3x + 1) + (4x + 5) + (3x + 1)

3x + 4x + 1 + 2x - 2 + 2x - 2 + 3x + 1 + 4x + 5 + 3x + 1

21x + 1 - 2 - 2 + 1 + 5 + 1

21x + 4

The  equation for the perimeter is

P = 21x + 4
