What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x) for which the function is defined.

Front

What is the range of a function?

Back

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

Front

What is a pattern in the context of functions?

Back

A pattern in functions refers to a consistent relationship between the input and output values, often expressed as a rule.

How do you identify a pattern in a set of ordered pairs?

Back

To identify a pattern, look for consistent changes in the input and output values, such as constant differences or ratios.

Front

What is the significance of the slope in a linear function?

Back

The slope indicates the rate of change of the function; it shows how much the output (y) changes for a unit change in the input (x).
