Domain and Range from a Graph (Exit Ticket)

Front

What is the definition of 'domain' in 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

What is the definition of 'range' in 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 domain of a linear function from its graph?

Back

To determine the domain of a linear function from its graph, identify the x-values that the graph covers.

Front

How do you determine the range of a linear function from its graph?

Back

To determine the range of a linear function from its graph, identify the y-values that the graph covers.

Front

What does it mean if a function has a domain of x < 5?

Back

It means that the function is defined for all x-values less than 5.

Front

What does it mean if a function has a range of y > 2?

Back

It means that the function produces output values (y-values) that are greater than 2.

Front

What is the domain of a quadratic function that opens upwards?

Back

The domain of a quadratic function that opens upwards is all real numbers.

Front

What is the range of a quadratic function that opens upwards?

Back

The range of a quadratic function that opens upwards is all real numbers greater than or equal to the minimum point.

Front

How can you represent a function with a restricted domain graphically?

Back

You can represent a function with a restricted domain by showing only the part of the graph that corresponds to the allowed x-values.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex of a quadratic function is the highest or lowest point on the graph, which helps determine the range.
