Domain and Range

Front

What is the definition of 'Domain' in a relation?

Back

The collection of all inputs or x-values.

Front

What is the definition of 'Range' in a relation?

Back

The collection of all outputs or y-values.

Front

Given the relation (2, 3), (4, 5), (6, 7), what is the range?

Back

{3, 5, 7}

Front

What is the domain of the relation (1, 2), (3, 4), (5, 6)?

Back

{1, 3, 5}

Front

How do you find the range from a set of ordered pairs?

Back

Identify all the second elements (y-values) from the ordered pairs.

Front

What is the range of the relation (0, -1), (1, 2), (2, 3)?

Back

{-1, 2, 3}

Front

If a function is defined as f(x) = x^2, what is the domain?

Back

All real numbers (x ∈ ℝ).

Front

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

Back

All real numbers greater than or equal to 0 (y ≥ 0).

Front

What does it mean if a relation has no range?

Back

It means there are no outputs (y-values) for the given inputs.

Front

Given the graph of a function, how can you determine the domain?

Back

Look for the x-values that the graph covers.
