What is a function?

Back

A function is a relation between a set of inputs (domain) and a set of possible outputs (range) where each input is related to exactly one output.

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

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 does it mean for a relation to be a function?

Back

A relation is a function if every input (x-value) is associated with exactly one output (y-value).

Front

Which of the following is NOT a part of a function? Input, Output, Relation, or Equation?

Back

Given the points (3, 5), (4, 9), (2, 5), which ordered pair could you add to create a function? (3, 7), (4, 1), (1, 9), (2, 6)

Back

(1, 9).

Front

What are the x-values in a set of points called?

Back

The x-values are called the domain.

Front

What are the y-values in a set of points called?

Back

The y-values are called the range.

Front

If a function has the points (3, 5), (2, 4), (9, 0), what could replace the ? in (?, 6) to create a non-function?

Back

3.

Front

What is the difference between a function and a non-function?

Back

A function has unique outputs for each input, while a non-function has at least one input that corresponds to multiple outputs.
