Domain and Range

Front

What is the definition of Domain in mathematics?

Back

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

Front

What is the definition of Range in mathematics?

Back

The set of all possible output values (y-values) for a function.

Front

How do you determine the Domain of a function from a graph?

Back

Identify the x-values that the graph covers from left to right.

Front

How do you determine the Range of a function from a graph?

Back

Identify the y-values that the graph covers from bottom to top.

Front

What does it mean if a value is included in the Domain or Range?

Back

It means that the value is part of the set, often indicated by a solid dot or bracket.

Front

What does it mean if a value is excluded from the Domain or Range?

Back

It means that the value is not part of the set, often indicated by an open dot or parentheses.

Front

If a function has a Domain of {-4, -1, 0, 2, 7}, what does this mean?

Back

The function can only take these specific x-values as inputs.

Front

If a function has a Range of {-1, 0, 2, 3}, what does this mean?

Back

The function can only produce these specific y-values as outputs.

Front

What is the Domain of the function represented by the graph that goes from -4 to 3?

Back

-4 ≤ x ≤ 3.

Front

What is the Range of the function represented by the graph that goes from -1 to 1?

Back

-1 ≤ y < 1.
