3x - 8 = 13 + -2(x

Please assist me with the domain and range of graphs

Sphinxa [80]

Answer: see below

<u>Step-by-step explanation:</u>

Domain represents the x-values from the smallest (furthest left) to the biggest (furthest right).

Range represents the y-values from the lowest (furthest down) to the highest (furthest up).

Interval notation: If a value is included <em>(closed dot)</em>, use a bracket [ ]

If a value is NOT included <em>(open dot)</em>, use a parenthesis ( )

Note that ± ∞ is never included.

1. Domain: smallest x-value is -4 (included). biggest x-value is 3 (included)

Range: lowest y-value is 2 (included). highest y-value is 5 (included)

D: x = [-4, 3] R: y = [2, 5]

2. Domain: smallest x-value is -∞ (←). biggest x-value is 2 (included)

Range: lowest y-value is 2 (included). highest y-value is ∞ (↑)

D: x = (-∞, 2] R: y = [2, ∞)

3. Domain: smallest x-value is -∞ (←). biggest x-value is ∞ (→)

Range: lowest y-value is -∞ (↓). highest y-value is ∞ (↑)

D: x = (-∞, ∞) R: y = (-∞, ∞)

4. Domain: smallest x-value is -∞ (←). biggest x-value is ∞ (→)

Range: lowest y-value is -∞ (↓). highest y-value is 4 (included)

D: x = (-∞, ∞) R: y = (-∞, 4]

5. Domain: smallest x-value is -∞ (←). biggest x-value is ∞ (→)

Range: lowest y-value is 3 (included). highest y-value is ∞ (↑)

D: x = (-∞, ∞) R: y = [3, ∞)

6. Domain: smallest x-value is -2 (included). biggest x-value is ∞ (→)

Range: lowest y-value is -3 (included). highest y-value is ∞ (↑)

D: x = [-2, ∞) R: y = [-3, ∞)

0.39<br> which is best buy<br> 0.41<br> 0.4.

Nana76 [90]

Answer:

0.39 because it's the cheapest / least

Step-by-step explanation:

Ok so we are trying to find the least. So first line up your decimals as shown below

<u>Tens</u> <u>Tenths</u> <u>Hundredths</u>

<h3> 0 . 3 9</h3><h3>---------------------------------------</h3><h3> 0 . 4 1</h3><h3>---------------------------------------</h3><h3> 0 . 4 0 ---> Imaginary 0</h3><h3 />

Now fill in any empty spaces with a 0 as shown in the decimal 0.4, your decimal will still have the same amount because 0.4 = 0.40 = 0.400 no matter how many 0's you put in the decimal.

When your done with placing 0's, look at the numbers in the first column, the Tens column. As you can see we have the numbers 0, 0, 0. They're all the same so we don't have to worry about that. Now lets go to the next column, the Tenths column. We have the numbers 3, 4, 4. Remember, we are finding the least amount. we know 3 is less than 4 so the decimal with the 3 in the Tenths place is the best buy. If these numbers were the same we would go on to the next place, the Hundredths place. If 2 of the decimals had a 3 in the Tenths place, you would eliminate the decimal with no 3 in the Tenths place and go on to the next place using only the decimals you have left.

So, <em>0.39</em> is the best buy.

Hope this helps you and makes Sense! :)

This is NOT copy pasted, I actually wrote all of this so that the person reading this answer can understand what I'm trying to explain.

Thank you, and have a Great Day! ;)
