A.2A Readiness - Domain and Range - Linear Functions

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

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 domain of a linear function?

Back

The domain of a linear function is typically all real numbers unless restricted by a specific context.

Front

How do you determine the range of a linear function?

Back

The range of a linear function is also typically all real numbers unless restricted by a specific context.

Front

What does it mean for a function to be continuous?

Back

A function is continuous if there are no breaks, jumps, or holes in its graph.

Front

What is the significance of the y-intercept in a linear function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis, representing the output value when the input is zero.

Front

How can you find the maximum value in the range of a function?

Back

To find the maximum value in the range, evaluate the function at the endpoints of the domain and any critical points within the domain.
