Domain and Range Practice

Front

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. Look for any restrictions such as vertical asymptotes or holes.

Front

What is the definition of 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 do you determine the range of a graph?

Back

To determine the range of a graph, identify the y-values that the graph covers. Look for any restrictions such as horizontal asymptotes or gaps.

Front

What does it mean if the domain is given as -7 ≤ x < 5?

Back

It means that x can take any value from -7 to just below 5, including -7 but not including 5.

Front

What does it mean if the range is given as y ≥ 1?

Back

It means that y can take any value greater than or equal to 1.

Front

What is the significance of the notation {2, 5, 8, 11} in relation to domain?

Back

This notation indicates that the domain consists of specific discrete values: 2, 5, 8, and 11.

Front

What does it mean if the range is given as -4 ≤ y ≤ 5?

Back

It means that y can take any value from -4 to 5, including both -4 and 5.

Front

What is the domain of a function represented by a set of points?

Back

The domain is the set of x-values from the given points.

Front

What is the range of a function represented by a set of points?

Back

The range is the set of y-values from the given points.
