Hi there!

[tex]\large\boxed{y = f(x) = log_{2}x}[/tex]

We can go through each given function and determine whether the graph is its representation:

y = f(x) = log₂x. The graph pictured is logarithmic as it contains a vertical asymptote (discontinuity) at x = 0.

y = f(x) = x². This equation contains a parabolic shape. This is incorrect.

y = f(x) = 2ˣ. This equation is an exponential, increasing function. This is incorrect.

Another way to check would be to use the point on the graph (1, 0), and plug the corresponding x and y values into each function.

For example:

0 = log₂(1) is correct.

0 = (1)² is incorrect.

0 = 2¹ is incorrect.

Answer:

The answer is y=f(x) = log2x

Answer:

(-4.5, 1.5)

Step-by-step explanation:

Answer:

1755.98

Step-by-step explanation:

1755.97809915

1 cent is 1 hundredth of a dollar, so to round to the nearest cent means to round to the nearest hundredth.

The 7 in boldface is the hundredths place.

Drop all digits to the right of the 7.

1755.97

dropped digits: 809915

Look at the leftmost digit that was dropped (in boldface). If it is from 0 to 4, you are done, and the answer is 1755.97. If the leftmost digit that was dropped is from 5 to 9, the hundredths digit goes up by 1. Here, the first digit that was dropped is an 8, so the 7 in the hundredth place goes up 1 to 8.

Answer: 1755.98

Answer:

40.82

Step-by-step explanation:

Answer:

13

Step-by-step explanation:

C = 2πr

81.64 = 2(3.14)r - divide both sides by 2

40.82 = 3.14r - divide both side by 3.14

13 = r

Answer:

x=8/3

Step-by-step explanation:

x+2x+17=25

3x+17=25

3x=8

x=8/3

Answer:

X = [tex]\frac{8}{3\\}[/tex]

Step-by-step explanation:

Answer:

X=2

Step-by-step explanation:

Using distributive property: 1/3(12x-24)=16

4x- 8=16

Using oposite oporations on both sides:

4x-8=16

4x+8=16-8

4x=8

8/4=2

x=2

Answer:

x=10

Step-by-step explanation:

x^2 - 10 - (9x) = 0

x^2 - 9x - 10 = 0

(x - 10) + (x + 1) = 0

x= 10

x = -1

Step-by-step explanation:

all of them are correct

there are 5 apples and 6 bananas

there are 6 bananas and 5 apples

5 apples plus 6 bananas=11

8 oranges+5 apples+6 bananas=19

so the ratio is 11:19

Answer:

they are all correct

Step-by-step explanation:

a ratio is a comparison saying that for every group of numbers that there will be another group of numbers for example

the ratio of apples to bananas is

                 number of apples->5:6<- number of bananas

so of the ratio stays the same then for every 5 apples added to the basket then 6 bananas will also be added(works other way to)

Answer:

m = 3

Step-by-step explanation:

Answer:

m = 3

Step-by-step explanation:

6m + 5 = m + 20

6m + 5 - 5 = m + 20 - 5

6m = m + 15

6m - m = m - m + 15

5m = 15

5m ÷ 5 = 15 ÷ 5

m = 3

no

Answer:

L=74

W=77

Step-by-step explanation:

Answer:

L=74 and W=77

Step-by-step explanation:

first the area of a rectangle is length of breath

A=L X W

4514= L X 61

61L=4514

L=4514/61

L=74m

b. perimeter =2(L + W)

338=2*92+ 2W

338=184+2W

2W=338-184

2W=154

W=154/2

W=74

hi

4 entries are  24   so one  entry is  24/4 = 6  

so 7 friends pay  6*7 = 42

Answer:

a = 4, x = 1

Step-by-step explanation:

The opposite sides of a parallelogram are congruent , then

WX = YZ , that is

a² + 5a = 5a + 16 ( subtract 5a from both sides )

a² = 16 ( take the square root of both sides )

a = ± [tex]\sqrt{16}[/tex] = ± 4

Since a > 0 , then a = 4

Also

XY = WZ , that is

x² + 6x = 4x + 3 ( subtract 4x + 3 from both sides )

x² + 2x - 3 = 0 ← in standard form

(x + 3)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 1 = 0 ⇒ x = 1

Since x > 0 , then x = 1

Answer:Hey I go to ohva the answer is c

Step-by-step explanation:I took the test

The option (C) versi-colour, because the difference between the minimum and Q1 is greater, is the correct choice.

A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.

We have:

A flower shop sells two types of Iris flowers: first flower and second flower.

The data is shown in the picture.

As we know, the median is the mid-value.

The min value for the first flower = 45

The min value for the second flower = 30

Q1 value for first flower = 51

Q1 value for second flower = 40

Difference between min and Q1 for first flower = 6

Difference between min and Q1 for second flower = 10

6 < 10

Thus, the option (C) versi-color, because the difference between the minimum and Q1 is greater, is the correct choice.

Answer:

[tex] m\angle XYZ = 70\degree [/tex]

Step-by-step explanation:

By exterior angle theorem:

4x° = 2x° + 70°

4x° - 2x° = 70°

2 x° = 70°

2x = 70

x = 70/2

x = 35

[tex] m\angle XYZ = 2x\degree [/tex]

[tex] m\angle XYZ = 2\times 35\degree [/tex]

[tex] m\angle XYZ = 70\degree [/tex]

Note:

Linear equations will never exponents in its equation such as

[tex] {x}^{2} \\ y = {x}^{3} [/tex]

as those equations will produce curly graphs.

Nonlinear equations will either contain exponents or logarithms (eg. ln2)
