Question

which of the following represent the range of the trigonometric function y=7sin(x)? 
1 (-7,7)
2[0,7)
3[-7,7]
4(-7,7]

anonymous · Answer

y = all real numbers, where -7 <= y <= 7

anonymous · Answer

ok but how do i know if its included or not

anonymous · Answer

If they are less than or equal to, the box is a bracket [ 

like that

anonymous · Answer

*or greater than or equal to

anonymous · Answer

[-7,7]

anonymous · Answer

ohh ok thxs

anonymous · Answer

how about this 
Which of the followning lines when drawn would not intersect the graph of y=6sin(x)
1x=8
2x=3
3y=-4
4y=9

anonymous · Answer

They all intersect, let me check again.

anonymous · Answer

anonymous · Answer

see i thought that but wasnt sure

anonymous · Answer

It would have to be a y=n, where n is above or below the range for 6sin(x)

anonymous · Answer

??

anonymous · Answer

The graph would have to be a outside of the range of 6(sin(x)) for no intersection to take place.

anonymous · Answer

oops.  Any y= equation where y= n where n is above 6, or y=n, where n is less than negative 6

anonymous · Answer

ok thxs
