Domain and Range

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 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

Identify the range of the following set of values: {1, 2, 4, 5}.

Back

{1, 2, 4, 5}

Front

Identify the domain of the following set of values: {(-2, 3), (0, 5), (2, 7)}. What are the x-values?

Back

{-2, 0, 2}

Front

What does it mean if a function is defined as f(x) = x^2?

Back

It means that for every input x, the output is the square of x. The domain is all real numbers, and the range is all non-negative real numbers.

Front

If the domain of a function is {1, 2, 3}, what can you say about its range?

Back

The range can vary depending on the function, but it will consist of the output values corresponding to the inputs 1, 2, and 3.

Front

What is the range of the function f(x) = 2x + 3?

Back

The range is all real numbers, as the function can produce any y-value depending on the x-value.

Front

How do you find the domain of a graph?

Back

The domain can be found by identifying all the x-values that the graph covers.

If a function has a domain of {-4 ≤ x ≤ 2}, what does this mean?

Back

It means that x can take any value from -4 to 2, inclusive.
