Domain and Range Practice

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

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 domain of the relation: (1, 2), (3, 4), (5, 6).

Back

The domain is {1, 3, 5}.

Front

Identify the range of the relation: (1, 2), (3, 4), (5, 6).

Back

The range is {2, 4, 6}.

Front

What is the domain of the function f(x) = √(x - 1)?

Back

The domain is x ≥ 1.

Front

What is the range of the function f(x) = x^2?

Back

The range is y ≥ 0.

Front

Identify the domain of the relation: (2, 3), (4, 5), (6, 7), (8, 9).

Back

The domain is {2, 4, 6, 8}.

Front

Identify the range of the relation: (2, 3), (4, 5), (6, 7), (8, 9).

Back

The range is {3, 5, 7, 9}.

Front

What is the domain of the graph of y = 1/x?

Back

The domain is all real numbers except x = 0.

Front

What is the range of the graph of y = 1/x?

Back

The range is all real numbers except y = 0.
