What is the domain?

Back

The Domain of a function is the set of all possible input values (x-values) that can be used in the function. For example, if the Domain is {-4, -1, 0, 2, 7}, these are the valid x-values.

Front

Which line has a slope of 0?

Back

A line with a slope of 0 is horizontal. For example, Line C is a horizontal line.

Front

What does it mean if a function is decreasing?

Back

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

Front

What is a horizontal line?

Back

A horizontal line is a line where the y-value remains constant regardless of the x-value, indicating a slope of 0.
