The amplitude is one-half the distance from the smallest value (38) to the largest value. (86)  (86 - 38)/2  =  24

The period is the x-distance that it takes to make one full wave:  one-half of a wave is made from 0 to 6, so one

full wave is made from 0 to 12:  12 = 0  =  12

The vertical shift is the shift from zero to the center y-value. The center y-value is 62, so the vertical shift is 62.
