##### Problem 2. Let T M2x20 (R) 5 M2x2(R) be the linear operator defined as3 T(A) = A - 4| 0 k Determine the value(s) of k s0 that T is an isomorphism_Hint for Problem 2: First get the matrix [T]B relative to basis B of M2x2(R). If [ were you; I would simply pick B as the standard basis. If you are struggling how to get [TJB, watch the first lecturc vidco of Weck 9 Then use the Thcorem: T : V _ V is injective if and only if [T]B is invertible wherc B is any basis of V Using [TlB to make the final con
