Question

What are the domain and range of each relation?

Answer 1

Answer:

Please check the explanation.

Step-by-step explanation:

• We know that the domain of a function is the set of input or argument values for which the function is real and defined.

Thus, the domain of the first relation is: {-2, -1, 0, 2}

• We also know that the range of a function is the set of values of the dependent variable for which a function is defined.

Thus, the range of the first relation is: {-4, -2, 2}

Given the second relation

x        y

-4      -2

-2       1

1         4  

4         4

• We know that the domain of a function is the set of input or argument values for which the function is real and defined.

Thus,

The domain of the second relation is: {-4, -2, 1, 4}

• We also know that the range of a function is the set of values of the dependent variable for which a function is defined.

Thus,

The range of the second relation is: {-2, 1, 4, 4}
