I thought the range was (0, 1) at first, but I see the confusion.

Wait, are you sure? I thought it could go beyond that.

It's definitely not [0, 1], that's for sure!

Totally agree, it's always been that way!

The range of sin x is definitely [-1, 1].
MA

I’m leaning towards option D, (-1, 1], because I remember the sine function reaching 1 but not going below -1.
NA

I think the range is definitely between -1 and 1, but I can't recall if it includes -1. I should have reviewed that part more.

I’m a bit unsure about the endpoints. Is the range [-1, 1] or (-1, 1)? I feel like I saw a similar question in practice.
CL
Clorinda

I remember that the sine function oscillates between -1 and 1, so I think the range should include those values.
LA

I'm a bit unsure about this one. The graph is centered around 0, but the question is asking about the range, which I think is different from the domain. Let me think this through step-by-step.

The range of a sine function is always between -1 and 1, so the answer should be C. (-1,1). I'm confident in this, as I've seen similar questions before.

Okay, I can see the graph of the sine function, but I'm not sure how to identify the range from this information. I might need to review my notes on sine functions to answer this properly.

Hmm, this looks like a straightforward question about the range of a sine function. I'll need to carefully analyze the graph to determine the minimum and maximum values.

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

Haha, this question is a real sin-nister trap. But I'm not falling for it, the answer is (-1,1).
ED

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

I always have to double check when it comes to closed intervals.
KA
Karina

Yeah, closed intervals always make me second guess my answer.
BL

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!

Oh, I see now. It's not about the domain, it's about the range.

C) (-1,1)
MA

A) [-1,1]
NO

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

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

Yes, the range of sin(x) is between -1 and 1.
RE
Rebeca

I think the answer is (-1,1).
IR
Irene

I disagree, I believe the range is (-1,1).
NO
Nobuko

I think the range is [-1,1].
