Question

Give the domain and range.

A: Domain: {-2,0,2} range {4,6,8}
B: Domain: {0,2} range {6,8}
C: Domain: {4,6,8} range {-2,0,2}
D: Domain: {6,8} range {0,2}​

Answer 1

Answer:

Option (a) is correct.

i.e. Domain: {-2,0,2} range {4,6,8}

Step-by-step explanation:

From the given diagram

The set X = {-2, 0, 2}

The set Y = {4, 6, 8}

We know that the domain of a relation is the set of all the x-values of the set X.

• In other words, the domain of relation would consist of all the input values.

Thus, the domain: {-2, 0, 2}

We know that the range of a relation is the set of all the y-values of the set Y.

• In other words, the range of relation would consist of all the output values.

Thus, the range: {4, 6, 8}

Hence, option (a) is correct.
