What are the domain and range of each relation? drag the answer into the box to match each relation

(1) The domain and range of figure is shown in option 3.  (2) The domain and range of the coordinate pairs is shown in option 2.

Explanation:

(1)

The values of x for which the function is defined are the domain of that function and range is the resultant values of the function at different value of x.

From The given figure it is noticed that the coordinates of the points are,

A coordinate pair is defined as (x,y).The values of x are -3,-3,-1,1,4. All sets contains only distinct elements so repetition of elements is not allowed.

Domain = {-3,-1,1,4}

The values of y are 1,-4,1,-1,4.

Range = {-4,-1,1,4]

So the correct option is third.

(2)

The given coordinates are,

The values of x are -4,-4,-3,1.

Domain = {-4,-3,1}

The values of y are 3,4,1,1.

Range = {1,3,4}

Therefore the correct option is (2).

step-by-step explanation:

im not sure what the answer is

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
