Front

What is the definition of Domain in a relation?

Back

The domain of a relation is the set of all possible input values (x-values) for which the relation is defined.

Front

Identify the domain of the relation: (-6,14), (0,32), (2,38), (4,44).

Back

-6, 0, 2, 4

Front

What is the definition of Range in a relation?

Back

The range of a relation is the set of all possible output values (y-values) that result from the input values in the domain.

Front

Identify the range of the graph that includes all real numbers.

Back

All real numbers

Front

What does the notation y ≥ 6 represent?

Back

It represents that the output values (y) are greater than or equal to 6.

Front

What does the notation y ≤ 6 represent?

Back

It represents that the output values (y) are less than or equal to 6.

Front

What is the range of the function if y > 0?

Back

The range is all real numbers greater than 0.

Front

What are the y-values in a relation called?

Back

Range

Front

What is the domain of the function if the inputs are 2, 4, 6, 8?

Back

The domain is 2, 4, 6, 8.

Front

If a function has a range of -10 ≤ y ≤ 6, what does this mean?

Back

It means the output values (y) can be any number from -10 to 6, inclusive.
