Hi just need a little help with the behaviour of this trig function(adsbygoogle = window.adsbygoogle || []).push({});

[tex] y=-3\cos (2x-\frac {\pi} {6}) +1 [/tex]

I converted the pi over 6 to degrees and got -30

need to state the period, amplitude, max/min values, range, domain, horizontal phase shift, and vertical dispacement.

So far after rearranging the the equation i have

period= [tex] pi [/tex]

range= ????

amplitude=?????

domain= all values XER

horizontal phase shift= 15 degrees left

vertical displacement= up 1

max\min ??? not sure how to figure this out from the equation i tried graphing using the graphing calculator but it wont give me the values for max and min. Therefore I cannot solve for amplitude yet and same with range.

CAN SOMEONE PLEASE HELP ME JUST NEED HELP WITH THE MAX AND MIN THANKS
