Domain and Range of Graphs

Front

What is the definition of 'domain' in relation to graphs?

Back

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

Front

What is the definition of 'range' in relation to graphs?

Back

The range of a graph is the set of all possible output values (y-values) that the function can produce.

Front

How do you determine the domain of a graph?

Back

The domain is determined by identifying the x-values that the graph covers, typically read from left to right.

Front

How do you determine the range of a graph?

Back

The range is determined by identifying the y-values that the graph covers, typically read from bottom to top.

Front

What does the notation [a, b] signify in terms of domain and range?

Back

The notation [a, b] indicates that both endpoints a and b are included in the set.

Front

What does the notation (a, b) signify in terms of domain and range?

Back

The notation (a, b) indicates that both endpoints a and b are excluded from the set.

Front

What does the notation [a, b) signify in terms of domain and range?

Back

The notation [a, b) indicates that endpoint a is included and endpoint b is excluded from the set.

Front

What does the notation (a, b] signify in terms of domain and range?

Back

The notation (a, b] indicates that endpoint a is excluded and endpoint b is included in the set.

Front

If a graph extends infinitely to the right, how is the domain expressed?

Back

The domain is expressed as [a, ∞) where 'a' is the leftmost point.

Front

If a graph extends infinitely upwards, how is the range expressed?

Back

The range is expressed as [b, ∞) where 'b' is the lowest point.
