<PRE><B>Question 953098</B>
For the following expression, state the amplitude and period of y, and sketch, on a separate diagram, its graph for the given interval.
 y=6cos(x/2)-4, 0&lt;_x&lt;_4 pie
 -----
amp = 6
period = (2pi)/(1/2) = 4pi
------------
{{{graph(400,400,0,4pi,-15,5,6cos(x/2)-4)}}}

Cheers,
