Let L: R3 ---> R3 denоte the lineаr trаnsfоrmаtiоn defined by: L(c1u1+c2u2+c3u3) = (c1+c2+c3)u1+ (2c1+c3)u2 -(2c2+c3)u3, where u1= , u2= , u3= . 1. Find the matrix of L with respect to the basis given by {u1, u2, u3}. (12 points) 2. Write the vector v = as a linear combination of the vectors u1, u2 and u3. (12 points) 3. Determine L(v).
