3. LINEARLY INDEPENDENCY 17 Solution Choose t 1 = - 1 , t 2 = 0 , and t 3 = 1 , f 1 (t 1 ) f 1 ( t 2 ) f 1 ( t 3 ) f 2 ( t 1 ) f 2 ( t 2 ) f 2 ( t 3 ) f 3 ( t 1 ) f 3 ( t 2 ) f 3 ( t 3 ) = 7 3 2 1 - 6 - 9 20 4 - 2 Compute the determinant, 7 3 2 1 - 6 - 9 20 4 - 2 = 50 , so the functions are linearly independent. a Project At beginning you should enter: Project title, your name, ss#, and due date in the following format Project One: Deﬁne and Graph Functions John Doe SS# 000-00-0000 Due: Mon.
