What is the definition of the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

How do you determine the domain of a graph?

Back

To determine the domain of a graph, identify the x-values that the graph covers, including any restrictions such as holes or asymptotes.

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

How can you find the range of a graph?

Back

To find the range of a graph, identify the y-values that the graph covers, including any gaps or restrictions.

Front

What does the notation {-5, -4, -3, -1} represent in terms of domain?

Back

This notation represents a discrete set of values that are included in the domain of the function.

Front

What is the difference between continuous and discrete domains?

Back

A continuous domain includes all values within a certain interval, while a discrete domain consists of specific, separate values.

Front

What is an inequality, and how is it used to describe the domain?

Back

An inequality is a mathematical statement that compares two values. It can be used to describe the domain by indicating the range of x-values that are valid for the function.

Front

What does the inequality -4 ≤ x ≤ 3 signify about the domain?

Back

It signifies that the domain includes all x-values from -4 to 3, inclusive.

Front

How do you express the domain of a function using interval notation?

Back

In interval notation, the domain is expressed as (a, b) for open intervals, [a, b] for closed intervals, and (a, b] or [a, b) for half-open intervals.

Front

What is the significance of identifying the domain and range in a function?

Back

Identifying the domain and range helps understand the behavior of the function and the values it can take.
