Question

What are the domain and range of the function represented by the set of

ordered pairs?
{(-11, 11),(-8, 8), (0, 0), (13, -13)}
A. Domain: -11 sxs 13
Range: -13 sys 11
B. Domain: {-11, -8,0, 13)
Range:{-13,0, 8, 11)
C. Domain: -13 sxs 11
Range: -11 sys 13
O
D. Domain:{-13,0, 8, 11}
Range: {-11, -8,0, 13)

Answer 1

Domain: {-11,-8,0,13}

Range: {11,8,0,-13}

Option B is correct option.

Explanation:

We need to find Domain and Range of given function:

{(-11, 11),(-8, 8), (0, 0), (13, -13)}

Domain:

Domain consists of Set of x coordinates

Range:

Range consists of Set of y coordinates

In the given function:

(-11,11) will have x-coordinate -11 and y-coordinate 11. So for every ordered pair we can find x and y coordinates.

{(-11, 11),(-8, 8), (0, 0), (13, -13)}

Domain: {-11,-8,0,13}

All elements of x coordinate. We take unique elements only

Range: {11,8,0,-13}

All elements of y coordinate. We take unique elements only. Order of elements is not important.

So, we get

Domain: {-11,-8,0,13}

Range: {11,8,0,-13}

Option B is correct option.
