With the help of given table first we plot the graph between x and y then by observation we find the graph similar to cosine graph with vertical translation 2 units , amplitude of 6 units and an interval of 8 units with no horizontal translation.

Hence the required trignometric function is y=6 cos(πx/4) + 2
