Back

If any vertical line passes through the graph of a relation no more than once, then it is a function.

How can you identify the domain of a function from its graph?

Back

The domain consists of all the x-values for which the function is defined.

Front

What is the significance of a slope of zero in a linear equation?

Back

A slope of zero indicates a horizontal line, meaning there is no change in y as x changes.

Front

What does it mean for a relationship to be non-proportional?

Back

It means that the relationship does not maintain a constant ratio between the quantities.
