The function can be expanded as follows:
y=3\ cos(4\theta+240)-2
The phase shift is:
\frac{240}{4}=60\ degrees
The period is:
\frac{2\pi}{4}=\frac{\pi}{2}

Q2 (median) = d5 = 2  //value in the middle
Q1 = (d2+d3) / 2 = (0+2)/2 = 1
(Q1 is middle value of d1,d2,d3,d4, but there is no middle element among four elements, that is why arithmetic mean is taken)
Q3 = (d7+d8) / 2 = (4+6)/2 = 5
interquantlie range = IQR = Q3 - Q1 = 5 -1 = 4

The triangle on the left area is 18 because the area of a triangle is 1/2 b times h so 12 times 3 times 1/2 equals 18.you then cut a triangle from the quadrilateral to make into a triangle.The triangle is the same height has other triangle so its area is 18.Since you took three for base of left and right triangle you subtract 6 from 1 to make it your base of 8 and your height is 12 and 12 tikmes  8 is 96 so 18+18+96=132 so our answer is 132.
