Determine the amplitude, period, and phase shift for the given function. Graph the function over one period. Indicate the $x$ -intercepts and the coordinates of the highest and Iowest points on the graph.
so we have. Ffx is equal to negative course. Sign X plus pi over four. The amplitude is one the PV It is to pike the phase shift, his negative pipe or four. And on the graph here you can see that the maximum point occurs where X is equal to three Piper four and the minimum point occurs. We're X is equal to seven pi over four.
