Is it just me, or does the graph look a little tilted? Maybe I need to adjust my angle of attack on this one.

I'm going with option D. Gotta love those closed intervals, they really get me every time.

I think option D is correct too. Closed intervals are tricky.

Wait, what? The question asks about the range of the function, not the domain. This is tricky!

But the graph shows that sin x never reaches -1 or 1, so it should be (-1,1).

The graph clearly shows the range of sin(x) is between -1 and 1, so the answer must be (-1,1).
