Domain and Range from a Graph

Front

What is the definition of Domain in a graph?

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 a graph?

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 from a graph?

Back

To determine the domain from a graph, identify the x-values that the graph covers. Look for the leftmost and rightmost points of the graph.

Front

How do you determine the range from a graph?

Back

To determine the range from a graph, identify the y-values that the graph covers. Look for the lowest and highest points of the graph.

Front

What is the domain of the function represented by the graph that spans from -3 to 3?

Back

-3 ≤ x ≤ 3

Front

What is the range of the function represented by the graph that spans from -7 to 2?

Back

-7 ≤ y ≤ 2

Front

What is the domain of the function represented by the graph that spans from -3 to infinity?

Back

-3 < x < ∞

Front

What is the range of the function represented by the graph that spans from negative infinity to 6?

Back

-∞ < y ≤ 6

Front

If a graph has a domain of -8 < x < 5, what does this mean?

Back

This means that the function is defined for all x-values greater than -8 and less than 5.

Front

If a graph has a range of -3 < y < 5, what does this mean?

Back

This means that the function produces y-values that are greater than -3 and less than 5.
