**a) T(x,y)= (x,2y)**

**b) vertical expansion**

Matrix for this for this transformation is A= 0 2 we for a transformation know T (3C) = A (SC) Multiply & Shords matrix for transtorm- ation by input get this. So Ho - T (GY) = 2 0 2 ។ Qy so T(xy) = (x, ay) b) by this transformation y value get expanded. So this is vertical expansion
