Graph the function for one period. Specify the amplitude, period, $x$ -intercepts, and interval(s) on which the function is increasing.
$$y=\sin (x / 2)-2$$
$x$ - Intercept
so we have. Why is equal to sign X over two minus truth. So first thing is, what's the amplitude of the amplitude is one. Next thing is the period. So the period is to fight divided by 1/2, and that's equal to four pi. And the next thing you want to talk about is the X intercept. So their car no X intercepts costing craft has not crossed E X axis at any point, and the next thing going to talk about is what is in double or which de function is increasing. So the function is increasing over the interval off or X s created that zero and less than pie and also where excess greeted and three pipe, but less than four pi.
