MATH 1271 Study Guide - Midterm Guide: Sign Your Name, Multiple Choice, Quotient Rule
Document Summary
Closed book, closed notes, no calculators/pdas; no reference materials of any kind. Turn o all handheld devices, including cell phones. Show work; a correct answer, by itself, may be insu cient for credit. Arithmetic need not be simpli ed, unless the problem requests it. I understand the above, and i understand that cheating has severe consequences, from a failing grade to expulsion. Sign your name: multiple choice, (5 pts) (no partial credit) let f be a function such that f(cid:48)(x) = 4e4x. Which of the following is an equation of the tangent line to the graph of f at (0, 1). Circle one of the following answers: (a) f(cid:48)/g(cid:48) (b) g(cid:48)/f(cid:48) (c) (gf(cid:48) f g(cid:48))/g2 (d) (f g(cid:48) gf(cid:48))/g2 (e) none of the above: (5 pts) (no partial credit) compute answers: d dx. 3x 4 (cid:12)(cid:12)(cid:12)(cid:12) (cid:12)(cid:12)(cid:12)(cid:12) (2x + 1)(3x + 4) 6 (2x + 1)(3x + 4) (e) none of the above: (5 pts) (no partial credit) compute [d/dx][sin2(xy)].
