Question
Each of J, K, L, M and N is a linear transformation from R2 to R².
These functions are given as follows:
J(x1, x2) = (3x1 – 5x2, –6x1 + 10x2),
K(x1, x2) = (-V3x2, V3x1),
L(x1, x2) = (x2, –x1),
M(x1, x2) = (3x1+ 5x2, 6x1 – 6x2),
N(x1, x2) = (-V5x1, /5x2).
Transcribed Image Text:Each of J, K, L, M and N is a linear transformation from R2 to R². These functions are given as follows: J(x1, x2) = (3x1 – 5x2, –6x1 + 10x2), K(x1, x2) = (-V3x2, V3x1), L(x1, x2) = (x2, –x1), M(x1, x2) = (3x1+ 5x2, 6x1 – 6x2), N(x1, x2) = (-V5x1, /5x2).
