Question

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

Answer 1

@rebeccaxhawaii maybe you can help?

Answer 2

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.

Answer 3

could i write it like -1 ≤ x ≤ 1

Answer 4

yes thats the correct domain.

Answer 5

NO

Answer 6

you are thinking od the range of sin x

Answer 7

-1 =< sin x <= 1

Answer 8

sin x can only have values in that range

Answer 9

thanks
