The given vector functions are solutions to the system x'( Ax(t) 3 4 X= e 8 -7 Determine whether the vector functions torm a fundamental solution set Select the correct choice below and fill in the answer box(es) to complete your choice. O A. No, the vector functions do not form a fundamental solution set because the Wronskian is O B. Yes, the vector functions torm a fundamental solution setbecause the Wronskian i The fundamental matrix for the system is State the general solution to the system x'(t) Ax() Select the berect choice below and, if necessary, fill in the answer box to complete your choice. O A The general solution is x(t) = O B. A general solution does not exist.
