Domain and Range - Practice

Front

What is the domain of a function?

Back

The set of all x-values for which the function is defined.

Front

What is the range of a function?

Back

The set of all y-values that the function can output.

Front

How do you determine the domain from a graph?

Back

Identify the x-values that correspond to the points on the graph.

Front

How do you determine the range from a graph?

Back

Identify the y-values that correspond to the points on the graph.

Front

What does it mean if a function has a restricted domain?

Back

It means that not all x-values are valid inputs for the function.

Front

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

Back

f(x) = 1/x, where x cannot be 0.

Front

What is the domain of the function f(x) = √(x-1)?

Back

x ≥ 1.

Front

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

Back

y ≥ 0.

Front

If a function is defined as f(x) = 2x + 3, what is its domain?

Back

All real numbers.

Front

If a function is defined as f(x) = -x^2 + 4, what is its range?

Back

y ≤ 4.
