Domain and Range & Unit 3 Vocabulary Review

Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output (y) for each input (x).

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

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

Front

How do you determine the domain from a set of ordered pairs?

Back

The domain can be determined by listing all the unique x-values from the ordered pairs.

Front

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

Back

The range can be determined by listing all the unique y-values from the ordered pairs.

Front

What is function notation?

Back

Function notation is a way to represent functions using symbols, typically written as f(x), where f is the function name and x is the input variable.

Front

What does it mean for a function to be defined on an interval?

Back

A function is defined on an interval if it has valid output values for all input values within that interval.

Front

What is the difference between an open interval and a closed interval?

Back

An open interval does not include its endpoints, while a closed interval includes its endpoints.

Front

How can you express the domain of a function using inequalities?

Back

The domain can be expressed using inequalities to show the range of x-values that are valid for the function.

Front

What is the significance of the range in real-world applications?

Back

The range can indicate the possible outcomes or results of a function in real-world scenarios, such as maximum and minimum values.
