Answer:
[tex]b.\:\: y=\sin(x),y=\cos(x)[/tex]
Step-by-step explanation:
The range of the sine and cosine functions is [tex]-1\le x\le1[/tex].
This means that the maximum value the basic sine and cone functions is 1 and the minimum value is -1.
This means that the two functions are bounded above and below.
The correct answer is B.
