Back

The range is the set of all possible output values (y values) for a function.

Front

What does it mean for a relation to pass the vertical line test?

Back

A relation passes the vertical line test if no vertical line intersects the graph at more than one point, indicating it is a function.

Front

If a relation has repeating x values, is it a function?

Back

No, if a relation has repeating x values that map to different y values, it is not a function.

Back

A function is increasing if, as x values increase, the corresponding y values also increase.

Front

What does it mean if a function is decreasing?

Back

A function is decreasing if, as x values increase, the corresponding y values decrease.
