Question

Identify which of the twelve basic functions listed below fit the description given

Answer 1

`b.\:\: y=\sin(x),y=\cos(x)`

Explanation:

The range of the sine and cosine functions is
`-1\le x\le1`.

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.
