Identifying Domain and Range

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) that the function can accept.

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

Identify the domain of the function: f(x) = x^2 for x in {1, 2, 3, 4, 5, 6}.

Back

Domain: {1, 2, 3, 4, 5, 6}

Front

Identify the range of the function: f(x) = x^2 for x in {1, 2, 3, 4, 5, 6}.

Back

Range: {1, 4, 9, 16, 25, 36}
