Domain and 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

If the domain is -3 ≤ x < 2, what does this mean?

Back

x can take any value from -3 to just below 2.

Front

What is the domain of the function if Li has at most $90 to spend on games costing $22.50 each?

Back

{0, 1, 2, 3, 4} (Li can buy 0 to 4 games).

Front

What is the domain of the graph if it is defined as -3 ≤ x ≤ 3?

Back

x can take any value from -3 to 3, inclusive.

Front

What does y ≥ 1 indicate about the range of a graph?

Back

The output values (y-values) start from 1 and go to infinity.

Front

If the range is y > 3, what does this mean?

Back

The output values (y-values) are greater than 3.

Front

How do you determine the domain from a word problem?

Back

Identify the constraints on the input values based on the context.

Front

What is an example of a domain restriction?

Back

If a function represents the number of items purchased, the domain cannot include negative numbers.

Front

What is the significance of the domain in a function?

Back

It defines the valid inputs for which the function is defined.
