Graph the function for one period. Specify the amplitude, period, $x$ -intercepts, and interval(s) on which the function is increasing.
$$y=-2-2 \cos 3 \pi x$$
$x=1 / 3$
so we have. Why is equal to negative two minus two course site. Three. High X So far, things was theon executes of the antic you just to and the senior is true pie divided by three pipe, which is equal to to over three, and then we need to find the X intercept. So there is wanted X intercept, which is at X is equal to one or 30 and then the graph is increasing over the interval where X is greater than zero, but it is less than 1/3.
