What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

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

Given the function {(0, 1), (1, -3), (2, -4), (-4, 1)}, what is the domain?

Back

D: {0, 1, 2, -4}.

Front

Given the function {(0, 1), (1, -3), (2, -4), (-4, 1)}, what is the range?

Back

R: {1, -3, -4}.

What are the x-values in a function called?

Back

The x-values are called the domain.

Front

What are the y-values in a function called?

Back

The y-values are called the range.

Front

If a function has the points (9, -2), (4, 3), (8, 10), (-4, 8), what is the range?

Back

{-2, 3, 8, 10}.

Front

What does it mean for a function to be one-to-one?

Back

A one-to-one function means that each x-value corresponds to a unique y-value, and no y-value is repeated.

Front

What is an example of a function?

Back

An example of a function is f(x) = 2x + 3, where each x-value gives a unique y-value.
