Domain and Range

Front

What is the Domain of a function?

Back

The collection of all inputs or x-values of a function.

Front

What is the Range of a function?

Back

The collection of all outputs or y-values of a function.

Front

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

Back

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

Front

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

Back

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

Front

What does it mean if a function has only one output for each input?

Back

It means the function is a valid function, adhering to the definition of a function.

Front

What is an example of a function?

Back

f(x) = 2x + 3, where for each x, there is one corresponding y.

Front

What is the output of the function f(x) = 2x + 3 when x = 4?

Back

Output: 11.

Front

What is the output of the function f(x) = x^2 when x = 3?

Back

Output: 9.

Front

For the relation (9, -2), (4, 3), (8, 10), (-4, 8), what is the Range?

Back

R: {-2, 3, 8, 10}.

Front

If the Domain is -3 < x ≤ 3, what does this mean?

Back

x can take any value greater than -3 and up to and including 3.
