Domain is all real numbers and range is [-3;3]

Explanation:

The sine function is repetitive and continuous and bounded between -3 and 3 and so since domain is all possible input x values, these are all real numbers, and since range is all possible output y values, these are all real numbers between -3 and 3, both endpoints included.
