Domain & Range

Front

What is the Domain?

Back

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

Front

What is the Range?

Back

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

Front

Identify the Domain: {-3, -1, 1, 3, 5, 7, 9}, {-3, -2, -1, 0, 1, 2, 3}, -3 ≤ x ≤ 3, -3 ≤ x ≤ 9

Back

{-3, -2, -1, 0, 1, 2, 3}

Front

Identify the Range: All real numbers, y ≥ 3, y > 3, 3 ≤ y ≤ 8

Back

y ≥ 3

Front

Identify the Domain: {-4, -1, 0, 2, 7}, {-5, -4, -1, 0, 1, 2, 4, 7}, {-5, 0, 1, 2, 4}, {5}

Back

{-4, -1, 0, 2, 7}

Front

Identify the Domain: -10 ≤ y ≤ 6, y ≤ 6, -10 ≤ x ≤ 6, All Real Numbers

Back

All Real Numbers

Front

Find the Range: All Real numbers, 0 < y < 11, y ≥ 0, y > 0

Back

y > 0

Front

What does it mean if a function has a Domain of All Real Numbers?

Back

It means that any real number can be used as an input for the function.

Front

What is a function's Range if it is defined as y = x^2?

Back

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

Front

How do you determine the Domain of a function from its graph?

Back

The Domain can be found by identifying the x-values for which the graph exists.
