Front

What test determines if a relation is a function based on vertical lines?

Back

Vertical Line Test

Front

What does it mean if a relation passes the vertical line test?

Back

Each input has only one output.

Front

What indicates a linear relationship in a table of values?

Back

A constant rate (slope) between the x and y values.

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

What is the horizontal line test?

Back

A test to determine if a function is one-to-one by checking if any horizontal line intersects the graph more than once.

Front

What is the difference between linear and non-linear functions?

Back

Linear functions have a constant rate of change, while non-linear functions do not.

Front

How can you identify a non-linear function from a table?

Back

If the outputs are not changing at a constant rate (e.g., doubling).

Front

What does it mean if a function has crossing arrows in a mapping diagram?

Back

It indicates that an input has more than one output, thus it is not a function.

Front

What is the definition of slope in a linear function?

Back

The rate of change of the function, calculated as the change in y over the change in x.
