Domain and Range EOC Review

Front

What is the definition of Domain in 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

What is the definition of Range in 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 do you determine the domain of a function from its graph?

Back

The domain can be determined by identifying the x-values for which the graph has points. It includes all x-values that the graph covers.

Front

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

Back

The range can be determined by identifying the y-values that the graph reaches. It includes all y-values that the graph covers.

Front

What is the domain of the function defined by the inequality -3 < x < 9?

Back

The domain is the set of all x-values such that -3 is less than x and x is less than 9.

Front

What is the range of the function defined by the inequality y ≥ 6?

Back

The range includes all y-values that are greater than or equal to 6.

Front

What does the notation -5 ≤ x ≤ 1 represent?

Back

This notation indicates that x can take any value from -5 to 1, inclusive.

Front

What does the notation -3 < y ≤ 2 represent?

Back

This notation indicates that y can take any value greater than -3 and up to 2, including 2.

Front

If a function has a domain of all real numbers, what does that mean?

Back

It means that the function is defined for every possible x-value.

Front

What is the significance of vertical lines in a graph regarding domain?

Back

Vertical lines indicate the x-values that are included in the domain. If a vertical line intersects the graph, that x-value is part of the domain.
