how to find domain and range of y=sinx

Question

anonymous · Answer

i don't think you find it, but rather you know it
the domain is all real numbers, and the range is between -1 and 1

Sometimes, there isn't much left to be said :)

anonymous · Answer

The domain is all real numbers.   The range is -1 to 1.. 

Think about a sin wave when answering this.. the domain is what possible X values you can get and the range is the possible Y values.

anonymous · Answer

makes sense. what about y=$$\sqrt{x+1}$$

anonymous · Answer

(-1, infinity) for the domain (remember, you can't take the square root of a negative number or zero)   range is (0 to infinity)   Open brackets to show that it doesn't include the -1 or the 0 :)
