Domain and Range

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: {(-6,14), (0,32), (2,38), (4,44)}.

Back

{-6, 0, 2, 4}

Front

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

Back

{14, 32, 38, 44}

Front

What is the domain of the graph represented by the points: (-4, 5), (0, 9), (2, -1), (3, 4)?

Back

{-4, 0, 2, 3}

Front

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

Back

{-2, 3, 8, 10}

Front

Identify the domain of the function f(x) = x^2 - 4.

Back

All real numbers (R) because any real number can be squared.

Front

Identify the range of the function f(x) = x^2 - 4.

Back

[-4, ∞) because the minimum value occurs at x=0.

Front

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

Back

All real numbers except x = 0.

Front

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

Back

All real numbers except y = 0.
