t3 + 1 1 1. Evaluate the limit if it exists (5 points): lim t--0o t3 + t2 -1 12. Apply limits to determine the horizontal and vertical asymptotes of the curve. That is, use calculus to show what the asymptotes are, and not methods from algebra/precalculus. (5 points) 2x2 + x - 1 f (x) = x2 - 3x - 4
