Identify the function that contains the data

Answers

Answer 1

Answer:

Answer:

Option D is correct.i.e., f(x) = | x - 2 | + 1

Step-by-step explanation:

Function which satisfy the given data is our Ans.

So, we check for all functions.

Option A : f(x) = |x| + 1

put, x = -2

we get, f( -2 ) = |-2| + 1 = 2 + 1 = 3 ≠ 5

⇒f ( -2 ) is not equal to given value of f ( -2 ).

Thus, This is not function of given data.

Option B : f(x) = | x-2 |

put, x = -2

we get, f( -2 ) = | -2 - 2 | = | -4 | = 4 ≠ 5

⇒f ( -2 ) is not equal to given value of f ( -2 ).

Thus, This is not function of given data.

Option C : f(x) = | x-2 | - 1

put, x = -2

we get, f( -2 ) = | -2 - 2 | - 1 = | -4 | - 1 = 4 - 1 = 3 ≠ 5

⇒f ( -2 ) is not equal to given value of f ( -2 ).

Thus, This is not function of given data.

Option D : f(x) = | x-2 | + 1

put, x = -2

we get, f( -2 ) = | -2 - 2 | + 1 = | -4 | + 1 = 4 + 1 = 5

⇒f ( -2 ) is equal to given value of f ( -2 ).

put, x = 0

we get, f( 0 ) = | 0 - 2 | + 1 = | -2 | + 1 = 2 + 1 = 3

⇒f ( 0 ) is equal to given value of f ( 0 ).

put, x = 2

we get, f( 2 ) = | 2 - 2 | + 1 = | 0 | + 1 = 0 + 1 = 1

⇒f ( 2 ) is equal to given value of f ( 2 ).

put, x = 3

we get, f( 3 ) = | 3 - 2 | + 1 = | 1 | + 1 = 1 + 1 = 2

⇒f ( 3 ) is equal to given value of f ( 3 ).

put, x = 5

we get, f( 5 ) = | 5 - 2 | + 1 = | 3 | + 1 = 3 + 1 = 4

⇒f ( 5 ) is equal to given value of f ( 5 ).

Thus, This is function of given data.

Therefore, Option D is correct.

greta made a desing with squares she colored 8 out of the 12 squares blue what fraction of the squares did she color blue

Answers

2/3 because 8/12 divided down is 4/6 which reduced again is 2/3

8/12 but you have to reduce which is 4/6 but then you reduce which is 2/3 and 2/3 can't be reduced so it is 2/3.

Answer:

The power is larger than the exponet

Step-by-step explanation:

A power is the product of multiplying a number by itself. A power is represented with a base number and an exponent. The base number tells what number is being multiplied. The exponent, a small number written above and to the right of the base number, tells how many times the base number is being multiplied.

Caley has a bag that contains 9 blue marbles and 13 yellow marbles. She selects a marble at random, and then, without replacing the first one, selects another marble at random. What is the probability that Caley selects a blue marble and then a yellow marble? Round your answer to the nearest percent. P(blue and yellow) ≈ %

Answers

The answer would be 24%.

You need to multiply the probabilities of each of those circumstances occurring separately (9/22 for choosing a blue one and 13/22 for choosing a yellow one) in order to find the probability of them happening in a row.

9/22 * 13/22 * 100% ~ 24%

B. solve the problem below.

A recipe calls for 9 tablespoons of milk for every 21 cups of flour. If the chef puts in 168 cups of flour, how many tablespoons of milk must the chef add?

Answers

Thing 1
A: If you use 32 gallons of gasoline you have to use 12 ounces of oil.
B: 6/16 and x/32. You would then cross multiply.

1A=12 oz
1B=16×2=32 6×2=12
32÷16=2
Since 32÷16=2 then you have to multiply 6 and 2 to get your answer which is 12oz
