Find the amplitude, period, and phase shift of the function. give the exact values, not decimal approximations.

Cosine is transformed in the form:

The amplitude is a

The period of cosine is:

And the phase shift is always by c, so that means our transformed functon in the form mentioned above looks like:

So our period is

Our phase shift is by units to the right

and our amplitude is 3.
