Warm- Up DOMAIN AND RANGE REVIEW

Front

What is the definition of 'Domain' in a function?

Back

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

Front

What is the definition of 'Range' in a function?

Back

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

Front

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

Back

To identify the domain from a set of ordered pairs, list all the unique x-values from the pairs.

Front

How do you identify the range from a set of ordered pairs?

Back

To identify the range from a set of ordered pairs, list all the unique y-values from the pairs.

Front

What is the domain of the relation represented by the set of points {(0,1), (1,-3), (2,-4), (-4,1)}?

Back

The domain is {-4, 0, 1, 2}.

Front

What is the range of the relation represented by the set of points {(0,1), (1,-3), (2,-4), (-4,1)}?

Back

The range is {-4, -3, 1}.

Front

What is the significance of identifying the domain and range in a function?

Back

Identifying the domain and range helps understand the behavior of the function and the values it can take.

Front

Can the domain of a function be infinite?

Back

Yes, the domain of a function can be infinite, such as in the case of polynomial functions.

Front

What is an example of a function with a restricted domain?

Back

A function like f(x) = 1/x has a restricted domain because x cannot be zero.

Front

What is the relationship between domain and range in a function?

Back

The domain consists of input values, while the range consists of output values resulting from those inputs.
