A2 - BW 12/3-12/4 Domain and Range from a Graph

Front

What is the definition of the domain of a function?

Back

The domain of a function is the complete set of possible values of the independent variable (usually x) for which the function is defined.

Front

What is the definition of the range of a function?

Back

The range of a function is the complete set of possible values of the dependent variable (usually y) that the function can produce.

Front

Identify the domain of the function represented by the graph that starts at x = -2 and goes to infinity.

Back

Front

Identify the range of the function represented by the graph that goes up to y = 16.

Front

What does it mean if a function has a domain of all real numbers?

Back

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

Front

If a function has a range of y ≥ 1, what does this indicate about its output values?

Back

This indicates that the function's output values start from 1 and go to infinity, meaning it cannot produce values less than 1.

Front

How do you determine the domain from a graph?

Back

To determine the domain from a graph, look for the x-values that the graph covers. Identify 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, look for the y-values that the graph covers. Identify the lowest and highest points of the graph.

Front

What is the domain of a function that is defined for x values from 0 to infinity?

Back

Front

What is the range of a function that has outputs starting from y = 2?

Back

The range is y ≥ 2.
