Question

Which of the following represents the domain and range of y = sin x?

Answer 1

Answer:

3rd choice

Step-by-step explanation:

The domain is (-infinity, infinity) because you can keep subtracting multiples of 360 until you get a value under 360. For the range, imagine a unit circle.

The y coordinate is the sin value, so it is just [-1, 1].

So the answer is the 3rd choice.

Answer 2

Answer: I just took the test and got 100%

1: C, Domain:(-infinite,infinite)

       Range: [-1,1]

2: D, Domain: -infinite< x < infinite, x =n pi, where n is an integer

        Range: -infinite < y < infinite

3: A, Domain: -infinite< x < infinite, x = pi/2, where n is an integer

Range: y _< -1 or y _> 1.... _< means less than, _> greater than or equal to :)

4: C, y= tan x

   D, y= cot x
