Domain and Range Of Linear Functions

Front

What is the definition of 'Domain' in the context of linear functions?

Back

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

What is the definition of 'Range' in the context of linear functions?

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 find the range of a graph?

Back

The range is found by reading the ends of the graph from bottom to top.

Front

How do you find the domain of a graph?

Back

The domain is found by reading the ends of the graph from left to right.

Front

What variable typically represents the range in a function?

Back

The variable 'y' typically represents the range.

Front

What is the range of the function represented by the graph with endpoints at (-2, 1)?

Back

The range is [-2, 1).

Front

What is the range of the function represented by the graph with endpoints at (-2, 2)?

Back

The range is [-2, 2].

Front

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

Back

It means that the function can accept any real number as an input.

Front

What does it mean if the range of a function is (a, b)?

Back

It means that the output values of the function are greater than 'a' and less than 'b', not including 'a' and 'b'.

Front

What is the significance of closed brackets [ ] in range notation?

Back

Closed brackets indicate that the endpoint values are included in the range.
