1. Consider an 3 D point [2, 2, 1]T. Perform a scaling operation (S) in both x axis and y axis by 5 units. a)[3, 3, 1]T b)[4, 4, 1]T c)[10, 1]T d)None of the above Answer is d). Scaling affects only two coordinates. Here scaling is performed about z axis so only x and y coordinates will undergo scaling from initial values. Multiply the x and y values with given scaling factor.

2. What is the other name of D 4 distance? a) city block distance b) chess board distance c) ring distance d) diamond distance Answer is a). D 4 distance between p(x, y) and q(s, t) is defined that |x s|+|y t|. So this clearly indicates that if we move from point p to point q then, how much distance I have to move along the x direction and how much distance I have to move along the y direction. Because |x – s| is the distance traveled along x direction and |y t| is the distance traveled along the y
