Domain and Range

Front

What is the definition of Domain in a function?

Back

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

Front

What is the definition of Range in a function?

Back

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

Front

How do you determine the Domain of a linear function?

Back

Identify the x-values that the function can take, often based on the context or restrictions given.

Front

How do you determine the Range of a function from a table of values?

Back

List all the unique y-values from the ordered pairs in the table.

Front

What is the Domain of the function f(x) = 2x + 3?

Back

All real numbers, or (-∞, ∞).

Front

What is the Range of the function f(x) = 2x + 3?

Back

All real numbers, or (-∞, ∞).

Front

Given the ordered pairs {(1,3), (2,6), (3,9)}, what is the Range?

Back

{3, 6, 9}.

Front

What is the Domain of the function represented by the graph with points (-4,0), (0,2), (4,4)?

Back

{-4, 0, 4}.

Front

If a function has a Domain of -3 < x ≤ 5, what does this mean?

Back

x can take any value greater than -3 and up to and including 5.

Front

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

Back

{-2, 3, 8, 10}.
