Suppose a 2D bounding box is given by (≤ is "less than or equal to"): -1≤x≤1 -10 ≤ y ≤ 10 Compute the new Bounding Box for the transformation given by the following matrix: (see section 9.4.4) 0.866 -0.5 0.5 0.866 Now enter the xmax for the new Bounding Box (round it to 3 decimal places, if needed).

17. Find the 4 by 3 matrix A that represents a right shift: (x1,x2, x3) is transformed to (0, x1,x2, x3). Find also the left shift matrix B from R4 back to R³, transforming (x1,x2, x3, x4) to (x2, x3, x4). What are the products AB and BA?
