Domain and Range Practice

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

If a function has a domain of all real numbers greater than -3 and less than or equal to 1, what does this mean?

Back

This means that the function can take any x-value from just above -3 up to and including 1.

Front

What is the range of the function c = 16.95x + 4.75 for x values between 4 and 7?

Back

The range is {72.55, 89.50, 106.45, 123.40}.

Front

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

Back

You look at the y-values that the graph reaches; the range is the set of these y-values.

Front

What is the difference between domain and range?

Back

Domain refers to the input values (x-values), while range refers to the output values (y-values) of a function.

Front

What does it mean if a function's domain is restricted?

Back

It means that not all x-values are allowed; only specific values can be used as inputs.

Front

Identify the range of the relation: {-6, 14, 2, 28}.

Back

The range is {14, 28}.

Front

What is the domain of the function f(x) = √(x + 4)?

Back

The domain is all real numbers greater than or equal to -4.

Front

If a function has a range of -2 ≤ y ≤ 3, what does this indicate?

Back

This indicates that the output values (y-values) of the function can be any number from -2 to 3, inclusive.
