Domain and Range Review

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

D: {1, 3, 5}

Front

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

Back

R: {2, 4, 6}

Front

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

Back

D: {x | x ≥ 1}

Front

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

Back

R: {y | y ≥ 0}

Front

For the function {(0, 1), (1, -3), (2, -4)}, write the domain and range.

Back

D: {0, 1, 2} R: {1, -3, -4}

Front

What is the range of the relation {(9, -2), (4, 3), (8, 10), (-4, 8)}?

Back

R: {-2, 3, 8, 10}

Front

What is the domain of the relation {(2, 5), (3, 7), (4, 9)}?

Back

D: {2, 3, 4}

Front

If a function has a domain of {0, 1, 2, 3} and outputs {2, 4, 6, 8}, what is the range?

Back

R: {2, 4, 6, 8}
