Question

What is the domain and range of the relation shown in the table?

x y
0 3
5 4
9 2
32 7

A)domain: {0, 5, 9, 32} range: y∈ℝ

B)domain: {0,5,9,32} range: {2,3,4,7}

C)domain: {2,3,4,7} range: {0,5,9,32}

D)domain: x range: {2,3,4,7}

Answer 1

The answer is  B. The domain is all of the x axis coordinates arranged from least to greatest and the  range is the y axis coordinated arranged form least to greatest!

Answer 2

The correct option is B.

Explanation:

Domain is the set of all possible inputs for which the function is defined.

Range is the set of all possible outputs.

The set all possible values of x for which the function is defined are known as domain and the set of all values of y are known as range.

The values of x are 0, 5, 9, 32, therefore the domain of the relation is

D = {0, 5, 9, 32}

The values of y are 3, 4, 2, 7, therefore the range of the relation is

R = {2, 3, 4, 7}

Therefore option B is correct.
