Unformatted text preview: MAC1140 Exam 2 - Fake Test 2 There are 17 questions, worth a total of 56 points (6 are extra credit) Two Point Questions. (1) Let f ( x ) = x n . Then f ( x ) has n- 1 turning points. (a) True (b) False (2) 0 is a complex number. (a) True (b) False (3) (Bonus!) If f ( x ) is even with domain (-∞ , ∞ ) , then f- 1 ( x ) is also even. (a) True (b) False (4) (Bonus!) What is the degree of f ( x ) = x (1- x 2 ) 2 ? (a) 1 (b) 2 (c) 4 (d) 5 (5) (Bonus!) If we know that x 2 + 4 is a factor of f ( x ) , then we can use synthetic division to nish factoring f ( x ) . (a) True (b) False (6) Find the range of f ( x ) = ( x + 1) 2- 2 , where x ≤ - 1 . (a) (-∞ , ∞ ) (b) [- 2 , ∞ ) (c) [- 1 , ∞ ) (d) (-∞ ,- 1] Four-point questions (7) A graph of f ( x ) shows that its end behavior is upwards to the left, downwards to the right. From this we know that: (a) f ( x ) has even degree and a n > (b) f ( x ) has even degree and a n < (c) f ( x ) has odd degree and a n > (d) f ( x ) has odd degree and...
