Web1. An easy way to find the vertical shift is to find the average of the maximum and the minimum. For cosine that is zero, but for your graph it is − 1 + 3 2 = 1. Therefore the vertical shift, d, is 1. Notice that the amplitude is the maximum minus the average (or the average minus the minimum: the same thing).
