Review carefully how in the Check at bottom of the slide we determined the polynomial P() from the coordinate vector [P]B. Use the same procedure to answer the following question: Consider the basis - {3t, 2t - 1} of P2. [plB = If [2], then O p(t) = 25t - 2 O p(t) = 5t - 1 O p(t) = 5t - 1 O p(t) - 6t2 - 3t O p(t) = 7+2t 10
