Unformatted text preview: MIDTERM 10/08 CALCULUS I - FALL 2008 Each question worths 20 points. Good luck! Have fun! (1) Take a look at the graph of this strange function f and answer the following questions (dont
need to justify anything7 just mark one of the options): (a) C‘id R ,1
iv) None of above. he domain of f is i
H e range of f is G v _’:H HVD-
% U (—170) U "'l (-1,0)U [1.2)
iv) None of above. AAA
0—! (C) is continuous on Zea. AAA
w—1 iv) None of above. ’ is well deﬁned on i the set where f is continuous,
” on a different set,
ii') I don’t know. ((1) A

even. non negative.
iv) None of above. (6) .—

(indicating for instance the cases where the limit is positive inﬁnity or negative inﬁnity). MIDTERM 10/08 2 (a)
lim (#4 + 11t2 + t — 1 — t2
lim lt _ l
t—t4 t — 4
(6) lim sec t tan t
t—n'r/2 (3) Using the deﬁnition of derivative compute f’(a:) where f is given by Check your answer using the quocient rule. (4) Find the derivatives of the following functions: (a)
(b) f(;r) = x2(cos(.r sin g(z) = (m sec 29v)3 (5) Using implicit differentiation ﬁnd the tangent line to the curve
m2 +4my+y2 = 13
at the point (2,1). (6) Match the graph of f and f’. (7) (Extra - no points) The distance between the towns A and B is 1000 miles. There is 3000
apples in A, and the apples have to be delivered to B through a desert road. The available
car can take 1000 apples at most. The car driver has developed an addiction to apples:
when he has apples aboard he eats 1 apple with each mile made. Figure out the strategy
that yields the largest amount of apples to be delivered to B. ...
