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

What is a function in mathematics?

Back

A function is a relation that assigns exactly one output value for each input value.

Front

What is the Domain of a function?

Back

The Domain of a function is the set of all possible input values (x-values) that the function can accept.

Front

How do you determine if a relation is a function?

Back

A relation is a function if each input value corresponds to exactly one output value.

Front

What does it mean for a mapping to be 'Not a Function'?

Back

A mapping is 'Not a Function' if at least one input value corresponds to multiple output values.

Front

What is the difference between Domain and Range?

Back

Domain refers to the input values of a function, while Range refers to the output values.

Front

What is an example of a function?

Back

(2, 3), (3, 5), (4, 7) is a function because each input has a unique output.

Front

What is an example of a relation that is not a function?

Back

(1, 2), (1, 3) is not a function because the input '1' has two different outputs.

Front

What does 'All real numbers' mean in the context of Domain?

Back

'All real numbers' means that any real number can be used as an input for the function.

Front

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

Back

The Range of f(x) = x^2 is y ≥ 0, since the output is always non-negative.
