Domain and Range

Front

What is the domain of a relation?

Back

The domain of a relation is the set of all possible input values (x-values) for the relation.

Front

What is the range of a relation?

Back

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

Front

How do you find the domain from a table of values?

Back

Identify all the unique x-values in the table.

Front

How do you find the range from a table of values?

Back

Identify all the unique y-values in the table.

Front

What does a negative slope indicate in a linear equation?

Back

A negative slope indicates that as x increases, y decreases.

Front

What does a positive slope indicate in a linear equation?

Back

A positive slope indicates that as x increases, y also increases.

Front

What is the slope of the line represented by the equation y = 2x + 3?

Back

The slope is 2.

Front

What is the slope of the line represented by the equation y = -4x + 1?

Back

The slope is -4.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input (x-value) has exactly one output (y-value).

Front

What is an example of a function?

Back

y = x^2 is a function because each x-value has one corresponding y-value.
