Objectives:- Interpret phase shifts and vertical translations- Graph trig graphs with translations- Write equations to describe translations
Sometimes it's hard to know how to do phase shifts. Here is another way to find your 5 main x-values to graph:
Set whatever is inside the trig function equal to the five x-values of and solve for x.
Solving these 5 short equations gives us 5 new x-valuesto graph. This is especially helpful when you have more than one transformation.
Once you have the x-values, the y-values are obtained from knowing the vertical shift & amplitude.
