The domain and the range of the graph are {-3,-2,0,2,3} and {-6,-5,-2,3,5}, respectively.

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

The domain of a function is the set of x values for which it is defined, whereas the range is the set of y values for which it is defined.

The domain of the given graph are the values of the x-coordinate that the function can take. Therefore, the domain of the given graph is,

Domain: {-3, -2, 0, 2, 3}

The range of the given graph are the values of the y-coordinate that the function can take. Therefore, the range of the given graph is,

Range: {-6, -5, -2, 3, 5}

Hence, the domain and the range of the graph are {-3,-2,0,2,3} and {-6,-5,-2,3,5}, respectively.

Complete the table of inputs and outputs for the function

Anon25 [30]

Answer:

x >>>>>>>> f(x)

–9 >>>>>> 10

–7 >>>>>>> 0

0 >>>>>>>> –35

5 >>>>>>>> –60

Step-by-step explanation:

f(x) = –5(x + 7)

1. x = –9, f(x) =?

f(x) = –5(x + 7)

f(x) = –5(–9 + 7)

f(x) = –5(–2)

f(x) = 10

2. f(x) = 0, x =?

f(x) = –5(x + 7)

0 = –5(x + 7)

Divide both side by –5

0 / –5 = x + 7

0 = x + 7

Collect like terms

x = 0 – 7

x = –7

3. x = 0, f(x) =?

f(x) = –5(0 + 7)

f(x) = –5(7)

f(x) = –35

4. f(x) = –60, x =?

f(x) = –5(x + 7)

–60 = –5(x + 7)

Divide both side by –5

–60 / –5 = x + 7

12 = x + 7

Collect like terms

x = 12 – 7

x = 5

SUMMARY:

x >>>>>>>> f(x)

–9 >>>>>> 10

–7 >>>>>>> 0

0 >>>>>>>> –35

5 >>>>>>>> –60

7. The amount of memory on a CD determines how many songs I can download to it.<br> Indep.<br> Dep.

galina1969 [7]

$\bf \underset{dependent}{\stackrel{\textit{songs I can download}}{S(M)}}~~=~~\underset{independent}{\stackrel{\textit{how much memory I have}}{M}}$

the memory is the independent, because that can vary at will, so it's independently varying at will, whilst the amount of songs are limited to how much memory there's in the CD, so the songs are dependent on the memory availability.

Please help I don't understand exponents

Mkey [24]

Answer:

1.) the answer is the fourth one, 1/5^7

2.) the answer is the fourth one, 1/5^6

3.) the answer is the fourth one, (2^6)^-5

4.) this is seems to be a duplicate of the first one

Step-by-step explanation:

1.) by 'adding' 4 exponent values on the top it simplifies the top to simply one and 5^7 on the bottom

2.) since this is an exponent of an exponent multiply them, getting 5^-6, then simplify negative exponents.
