Domain and Range Practice

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

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

Front

What does it mean if the domain is 'All real numbers'?

Back

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

Front

If the domain is x ≥ 0, what does this indicate?

Back

The function only accepts non-negative input values.

Front

What is the relationship between domain and range?

Back

The domain consists of input values, while the range consists of output values derived from those inputs.

Front

How do you determine the domain from a graph?

Back

Identify the x-values that the graph covers from left to right.

Front

How do you determine the range from a graph?

Back

Identify the y-values that the graph covers from bottom to top.

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

What is an example of a function with a limited domain?

Back

f(x) = √x, where the domain is x ≥ 0.

Front

What is an example of a function with a limited range?

Back

f(x) = x^2, where the range is y ≥ 0.
