Use the domain and range of each of the following relations to determine which is a function. A. {(–4, 3), (–2, –1), (–4, 8)} B.

Leya [2.2K]

Answer:

Option B and Option C.

Step-by-step explanation:

A relation is a function if there exist a unique output for each input.

If a relation is defined as

$R=\{(x,y),x\in R,y\in R\}$

then relation R is a function if there exist a unique value of y for each value of x.

In option A, the given relation is

{(–4, 3), (–2, –1), (–4, 8)}

Domain = {-4,2}

Range = {3,-1,8}

It is not a function because at x=-4 we have more than one output value, y=3 and y=8.

In option B, the given relation is

{(–4, 3), (–2, –1), (–7, 8)}

Domain = {-4,-2,-7}

Range = {3,-1,8}

It is a function.

In option C, the given relation is

{(–4, –2), (–7, 7)}

Domain = {-4,-7}

Range = {-2,7}

It is a function.

In option D, the given relation is

{(–4, 3), (–2, –1), (–2, –8), (–7, 8)}

Domain = {-7,-4,-2}

Range = {-8,-1,3,8}

It is not a function because at x=-2 we have more than one output value , y=-1 and y=-8.

Therefore, the correct options are B and C.

What ia the angle of AOC and DOE

natulia [17]

(i) Angle AOC would equal 48°, as it is vertically opposite to angle DOB and they are therefore equal.

(ii) Angle DOE would equal 42°. We can see this because angles on a straight line add up to 180°, and 90 + 48 = 138, so we can do 180 - 138 = 42°.

I hope this helps!

Which of the following statements are true for the Child dependency ratio for the northeast region

Colt1911 [192]

Option C and D is correct.

Dependency Ratio: It is the ratio of number of dependents to the total working population in a region.

In option A and B, we are provided with the information that 27% of the workers or people are children. No information is provided about dependency ratio.

In option C and D, 270 children and 27 children are dependent on 1000 workers and 100 workers respectively. It provides the information about the dependency ratio.

In option E, it is given that 270 children for every 1000 people not for working people. So, the information provided in option E is not the dependency ratio.

Hence, option C and D are correct as these option provides the information about the child dependency ratio for the northeast region.
