Question

@UglyTurtle Can you help me please? :)

Answer 1

That is false. The domain of sin(x) is all real numbers, or (-inf, inf). However, the range of sin(x) is indeed -1=< y <= 1

Answer 2

I have 2 more if you can help me?

Answer 3

This is also false correct?

Answer 4

Err, is there a reason you're asking us? You don't know what domain and range are? You don't know what the graphs look like?

Answer 5

I just don't understand it? :/

Answer 6

The domains are the inputs and the range are the outputs.

Answer 7

And what does that mean?

Answer 8

Doesn't the answer have to be false? Because cos(x) takes values from -1 to 1.

Answer 9

It does take those values, but those aren't the only values it can take.

Answer 10

What else can it take?

Answer 11

It can take any number from -inf to +inf, all real numbers. That is the domain of the function, what inputs are you allowed to plug into the function.

Answer 12

We're looking for the range though.

Answer 13

Right. It's easier if you are able to see a graph of cos(x). However, it is similar to sine. The range of cos(x) is -1 <= y <= 1

Answer 14

Is the answer for this question True or False? I need to go to sleep and this is my last question..

Answer 15

Well, what do you think? I pretty much explained the answer for you. The y-value of cos(x) go from -1 to 1. Do they only go from -1 to 0?

Answer 16

True.

Answer 17

No, try again.

Answer 18

What... I said false earlier and you said it was incorrect.

Answer 19

I didn't say anything about your answer. I wanted to know what you didn't understand.

Answer 20

Alright. Thanks for answering. Night
