Domain and Range

Front

What is the domain of a function?

Back

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

Front

Identify the domain of the relation: (0, 1), (2, 3), (4, 5).

Back

The domain is {0, 2, 4}.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

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

Back

The range is {2, 4, 6}.

Front

How do you find the domain from a graph?

Back

To find the domain from a graph, look for the x-values that the graph covers.

Back

The domain is {x | x ≥ 1}.

Front

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

Back

The range is {y | y ≥ 0}.

Front

Identify the domain of the function f(x) = 1/(x-3).

Back
