Mahon, Kevin – Review 1 – Due: Dec 9 2005, 6:00 pm – Inst: Edward Odell 1 This print-out should have 19 questions. Multiple-choice questions may continue on the next column or page – fnd all choices beFore answering. The due time is Central time. Review one covers the material on test 1, namely it covers sections 2.1-2.3,2.5,2.6,3.1- 3.4. While you can submit answers and get a score as usual this counts 0 001 (part 1 oF 1) 10 points AFter t seconds the displacement, s ( t ), oF a particle moving rightwards along the x -axis is given (in Feet) by s ( t ) = 6 t 2 - 8 t + 3 . Determine the average velocity oF the particle over the time interval [1 , 3]. 1. average vel. = 15 Ft/sec 2. average vel. = 14 Ft/sec 3. average vel. = 13 Ft/sec 4. average vel. = 12 Ft/sec 5. average vel. = 16 Ft/sec 002 (part 1 oF 1) 10 points Below is the graph oF a Function y = f ( x ) 2 4 6 - 2 - 4 - 6 2 4 6 8 - 2 - 4 Use the graph to determine the right hand limit lim x 2+ f ( x ) . 1. the limit does not exist 2. lim x 2+ f ( x ) = 4 3. lim x 2+ f ( x ) = 2 4. lim x 2+ f ( x ) = 0 5. lim x 2+ f ( x ) = - 4 003 (part 1 oF 1) 10 points A Function f is defned piecewise For all x 6 = 0 by f ( x ) = 5 + x, x < - 2 , 3 2 x, 0 < | x | ≤ 2 , 3 + x - 1 2 x 2 , x > 2 . By frst drawing the graph oF f , determine all the values oF a at which lim x a f ( x ) exists, expressing your answer in interval no- tation. 1.
