Question: 2. (a) (6 pts) Let 7 : R2 -> R2 be the linear transformation that first reflects points through the horizontal x1-axis and then rotates

2. (a) (6 pts) Let 7 : R2 -> R2 be the linear transformation that first reflects points through the horizontal x1-axis and then rotates points through -7/2 radians. Find the standard matrix for T. (b) (4 pts) Let : R2 -> R2 be a linear transformation such that T(x1, 12) = (21 + 12, 4x1 + 5x2). Find x such that T(x) = (3, 8)
