a).Given the transformation matricesT1 = #((2,1),(-1,-2))# and T2 = #((3,1),(1,3))#And that transformation T1 followed by T2 can be replaced by a single transformation T, write down the matrix for T.b).Find the inverse of matrix T.c).The points A”(7,-11), B”(-7,-13),C”(-8,16) and D”(8,8) are the images, of points A,B,C and D respectively under transformation T1 followed by T2 ..Write down the coordinates of A,B,C and D.
