What is the domain of f(x) = sin(x)?

OpenStudy (anonymous):

@rebeccaxhawaii maybe you can help?

OpenStudy (hurgleman):

When looking for the domain of a function, you're looking to find what values CAN be put into a function. Things to keep in mind when looking for a domain are variables in the denominator, or equations that have vertical asymptotes. f(x) = sin(x) has a domain of \[(-\infty, \infty)\] You can find this by finding any breaks in the Y axis. If any value of X can be put in, the domain is infinite in either directions.

could i write it like -1 ≤ x ≤ 1

OpenStudy (welshfella):

yes thats the correct domain.

OpenStudy (welshfella):

NO

OpenStudy (welshfella):

you are thinking od the range of sin x

OpenStudy (welshfella):

-1 =< sin x <= 1

OpenStudy (welshfella):

sin x can only have values in that range

thanks
