Amplitude (if applicable, give the answer in fractional form)

Period (in radians as a multiple of pi - note: do not write "rad" or "radians" in your answer)

Phase Shift (if the shift is right, enter + and if to the left, enter - before the number; if none, enter the number zero)

y = 3cos 3(x + π/3)

amplitude : 3

period = 2π/3

phase shift: π/3 to the left
