Question

The domain of y = sin x is the set of _______. all real numbers > 0 real numbers all real numbers < 0 all real numbers > x

Answer 1

The domain of y = sin x is the set of all real numbers.

The sine function, represented by y = sin x, is defined for all real numbers, meaning that any real number can be plugged into the function as the input (x) and will produce a valid output (y). Therefore, the domain of y = sin x is the set of all real numbers.
