Determine whether the given vector functions are linearly dependent or linearly independent on the interval ( - co, co). 8 2 Let X1 = 4 and X2 = Select the correct choice below, and fill in the answer box to complete your choice. 8t 8 O A. The vector functions are linearly dependent since there exists at least one point t in ( - co,co) where det x, (t) x2(t)] is 0. In fact, det x, (1) x2(t)] = O B. The vector functions are linearly independent since there exists at least one point t in ( - co, co) where det x, (t) x2(t)] is not 0. In fact, det x, (1) x2(t)] =] O C. The vector functions are linearly independent since there exists at least one point t in ( - co,co) where det x, (t) x2(t) ] is 0. In fact, detfx, (t) x2(t)] =]. O D. The vector functions are linearly dependent since there exists at least one point t in ( - co,co) where det x, (t) x2 (t)] is not 0. In fact, det x, (t) x2(1)] =]
