Each of J, K, L, M and N is a linear transformation from R2 to R2. These functions are given as follows: J(21, 22) = (5x15x2,-101 +102), K(1,2)=(√5x2, √5x1), L(1,2)=(2, -1), M(x1, x2) = (5x1 + 5x2, 10x1 - 6x2), N(1, ₂) = (-√51, √5x2). (a) In each case, compute the determinant of the transformation det J- det K- det L- ,det M- det N- (b) One of these transformations involves a reflection in the vertical axis and a rescaling. Which is it?
