Front

What is the definition of 'domain' in a relation?

Back

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

Front

What is the definition of 'range' in a relation?

Back

The range of a relation is the set of all possible output values (y-values) that result from the input values in the domain.

Front

Back

The domain is {-6, 0, 2, 4}.

Front

Identify the range of the relation: {-3, 1, 2, 5}.

Back

Front

What are the x-values in a relation called?

Back

The x-values are called the domain.

Front

What are the y-values in a relation called?

Back

The y-values are called the range.

Front

How do you determine the domain from a set of ordered pairs?

Back

The domain is determined by listing all the first elements (x-values) of the ordered pairs.

What is the domain of the function f(x) = 1/(x-2)?

Back

The domain is all real numbers except x = 2.

Front

What is the range of the function f(x) = x^2?
