If you were given the function f(x) and its inverse function,{f}^( - 1)(x)
, what would you expect the values of
{f}^( - 1)(f(3))
to be, assuming that 3 is part of the domain of f(x)? Explain your answer.​

Answers

Answer 1
Answer:

Answer:

3

Step-by-step explanation:

if we combine a function f(x) and its inverse f-¹(x), the result will be x

f-¹(f(x)) = f(f-¹(x)) = x

you can try for any function, i.e.

f(x) = 2x + 1

f-¹(x) = (x-1)/2

f-¹(f(x)) = (2x + 1 - 1)/2 = x

f(f-¹(x)) = 2((x-1)/2) + 1 = x - 1 + 1 = x

What measure of center best represents the data set? Data Set {27, 29, 26, 28, 25} A; mean only B; medium only. C; mode only D; mean or medium

Answers

The measure of center that best represents the data set is (D) mean or medium

The data set is given as:

{27, 29, 26, 28, 25}

Rearrange the set as follows:

{25, 26, 27, 28, 29}

In the above set, we have the following highlights

  1. The elements are consecutive numbers
  2. There is no outlier in the set

The mean and the median of a dataset that has consecutive numbers are equal

Hence, the measure of center that best represents the data set is (D) mean or medium

Step-by-step explanation:

Hollis house is located at (-1,4). She can walk in a straight line to get to Jedds house. A fast food resturant is located at (-3,2) and partitions the way from hollis house to jedds house by a ration of 1:2 find the coordinates of jedds house

Answers

Answer:

The coordinates of Jedds house are (-7 , -2)

Step-by-step explanation:

* Lets explain how to solve the problem

- If point (x , y) divide the distance between the two points

  (x_(1),y_(1)) and (x_(2),y_(2)) at the ratio

  (m_(1):m_(1)), then

  x=(x_(1)m_(2)+x_(2)m_(1))/(m_(1)+m_(2)) and

  y=(y_(1)m_(2)+y_(2)m_(1))/(m_(1)+m_(2))

* Lets solve the problem

∵ Hollis house is located at (-1 , 4)

∴ (x_(1),y_(1)) = (-1 , 4)

∵ She can walk in a straight line to get to Jedds house

∵ The restaurant is located at (-3 , 2) and partitions the way from

   Hollis house to Jedds house by a ration of 1 : 2

∴ (x , y) = (-3 , 2)

∴ (m_(1):m_(1)) = 1 : 2

- Lets consider that Jedds house is located at (x_(2),y_(2))

∴ -3=(-1(2)+x_(2)(1))/(1+2)

∴ -3=(-2+x_(2))/(3)

- Multiply both sides by 3

∴ -9=-2+x_(2)

- Add 2 for both sides

∴ -7=x_(2)

∴ 2=(4(2)+y_(2)(1))/(1+2)

∴ 2=(8+y_(2))/(3)

- Multiply both sides by 3

∴ 6=8+y_(2)

- Subtract 8 for both sides

∴ -2=y_(2)

∴ The coordinates of Jedds house are (-7 , -2)

Answer:

(-7 , -2)

The above answer is correct

What fraction of 130 is 80


Answers

The fraction should be (8)/(13)

Calculation of fraction:

Since the two numbers are given 130 and 80

We have to know about the fraction

So, the fraction should be

= 80/ 130\n\n= 8/ 13

Learn more about the fraction here: brainly.com/question/1786648
This is an unusual question, since they commonly ask for the percentage of the number. Nevertheless,
(80)/(130)=(8)/(13)
Therefore 80=130((8)/(13))

15 POINTS PLS ANSWER! A bagel shop sells bagels by the half dozen. The table at the right shows the number of bagels a shop gives per ​"half dozen​" ordered. Write an algebraic expression that gives the rule for finding the number of bagels in any number b of half dozens.

Answers

Answer:

The expression that gives the number of bagels is 6b.

Step-by-step explanation:

The given table is ;

6    36

7    42

8    48

b    ----

Let 'b' represents the bagels in any number of half dozen.

Let the total number of bagels be represented by x.

Now, we can represent the situation as follows:

x=6b

The expression that gives the number of bagels is 6b.

We can check this also.

When b = 7, we get x = 42

when b = 8, we get x = 48

9×6=54

(6 is a half dozen)

The table shows that each part it multiplied by 6,

6×6=36

7×6=42

8×6=48

(b) represents nine, and six is a half a dozen, so,

(b)9×6 (half a dozen)
