phase shift = −0.5 (or 0.5 to the right) vertical shift D = 3. In words: the 2 tells us it will be 2 times taller than usual, so Amplitude = 2. the usual period is 2 π, but in our case that is "sped up" (made shorter) by the 4 in 4x, so Period = π/2. and the −0.5 means it will be shifted to the right by 0.5.
