Thread: graphing

I'm trying to graph:

3cos[(pi/2x)+(6pi/5)] within the interval [8,-8],

but I'm not getting the right answer when I plot the points. I have one of the points at (-2.4,3) and the rest of the graph should follow given I can only move one point on the graph and the rest of the graph will follow in accordingly

Is your function or ?

My function is the first one function you put down. Sorry.
